Inside

The AMD Ryzen 9 9900X3D and NVIDIA GeForce GTX 1660 Ti pairing in Inside produces a dataset that is surprisingly GPU-bound at higher resolutions, yet the CPU’s massive thread count and cache ensure that even the most demanding preset remains fluid. The measured results show a clear hierarchy: the GTX 1660 Ti is the limiting factor at 4K, but the Ryzen 9 9900X3D’s single-thread strength keeps 1080p performance exceptionally high. This analysis breaks down the scaling, component roles, and optimal settings based strictly on the measured FPS data.

Resolution Scaling

The FPS drop from 1080p to 4K is steep and directly attributable to the GPU’s pixel throughput limits. At High settings, the average FPS falls from 108 at 1920x1080 to 78 at 2560x1440, then to 49 at 3840x2160. That is a 55% reduction from 1080p to 4K, which indicates the GTX 1660 Ti’s 84.96 GPixel/s pixel rate is being saturated as resolution climbs. The scaling is non-linear; the jump from 1440p to 4K costs 29 FPS, while the jump from 1080p to 1440p costs 30 FPS, showing that the GPU’s fillrate is the dominant constraint beyond 1440p.

At Low settings, the story is similar but with higher absolute numbers. The average FPS at 1080p Low is 216, dropping to 155 at 1440p and 98 at 4K. This 118 FPS total drop from 1080p to 4K is a 55% decline, identical in percentage terms to High settings. This consistency suggests the limiting factor is not shader complexity but rather the ROP throughput and memory bandwidth of the 288.0 GB/s GDDR6 bus. The GPU’s 48 ROPs must fill more pixels at 4K, and the 192-bit memory bus struggles to feed them, regardless of the preset.

Ultra settings show the harshest scaling. At 1080p Ultra, the average is 103 FPS, which drops to 74 at 1440p and 46 at 4K. The 4K Ultra result is only 45% of the 1080p Ultra figure, confirming that the GTX 1660 Ti’s 5.437 TFLOPS FP32 performance is insufficient for 4K Ultra in Inside. Meanwhile, Medium settings provide a middle ground: 173 FPS at 1080p, 124 at 1440p, and 78 at 4K. The delta between Medium and High at each resolution is consistently around 25%, which indicates that the game’s engine scales shader load predictably, but the GPU’s absolute limits are hit first at 4K.

The data reveals that 1440p is the sweet spot for this combo. At High settings, 1440p delivers 78 FPS, which is 59% higher than the 4K result and only 28% lower than 1080p. This suggests the Ryzen 9 9900X3D has ample headroom to feed the GPU at 1440p, but the GTX 1660 Ti cannot keep up beyond that resolution. For 4K gaming, only Low settings approach playability at 98 FPS, while Medium and High dip below 80 FPS, and Ultra drops to 46 FPS. Benchmark results indicate that the CPU is never the bottleneck in this scenario; the GPU’s 6 GB VRAM and 288.0 GB/s bandwidth are the walls.

CPU Role

The AMD Ryzen 9 9900X3D is a 12-core, 24-thread processor with a base clock of 4.40 GHz and a boost of 5.50 GHz. In Inside, a puzzle platformer that is not heavily threaded, the CPU’s single-thread performance is the primary contributor. The Geekbench single-core score of 3041 and Cinebench R23 single-core score of 6739 place it in the top tier, and the measured FPS at 1080p Low (216 FPS) shows that the CPU can drive frame rates far beyond what the GTX 1660 Ti can render at higher resolutions. The PassMark single-thread score of 4646 further confirms that the Ryzen 9’s per-core speed is sufficient for this game’s logic and physics.

The CPU’s large 128 MB L3 cache is also relevant. Inside features tight corridors and repeated asset loading, and the 3D V-Cache technology (implied by the X3D suffix, though not explicitly stated in the pack) helps reduce memory latency. The Cinebench R20 single-core score of 2830 and 3DMark 2-thread score of 2512 indicate that even with two threads, the CPU can handle the game’s main thread and a secondary worker thread without stalling. The 24 threads are overkill for Inside, but they ensure that background tasks never interfere with frame pacing.

Relative to rivals, the Ryzen 9 9900X3D’s average benchmark score of 54762 is 1.3% ahead of the Intel Core Ultra 5 245K (score 54053) and 2.1% ahead of the Intel Core i7-14700F (score 53620). It trails the Intel Core Ultra 5 245KF by 0.6%, but that difference is negligible in a game like Inside. The CPU’s percentile ranking of 91 against all CPUs means it outperforms 91% of processors, which is why the 1080p Low result of 216 FPS is achievable. The data shows that the CPU is not the constraint; even at 4K Ultra (46 FPS), the Ryzen 9 9900X3D has plenty of cycles left, as evidenced by the 3DMark max-threads score of 13795.

The CPU’s boost clock of 5.50 GHz is critical for maintaining high average FPS in scenes with many dynamic objects. The PassMark physics score of 5340 suggests strong integer and floating-point throughput, which helps with collision detection and particle effects. However, the game’s low thread count means the CPU’s 12 cores are mostly idle, yet the single-thread headroom ensures that minimum FPS never dips below the GPU’s output. In summary, the Ryzen 9 9900X3D is overqualified for Inside, and its role is to ensure the GPU is the only limiting factor.

GPU Role

The NVIDIA GeForce GTX 1660 Ti is the bottleneck in this configuration, but it is a capable one for Inside at lower resolutions. With 6 GB of GDDR6 memory on a 192-bit bus, the GPU delivers 288.0 GB/s of bandwidth, which is sufficient for 1080p and 1440p but strained at 4K. The 48 ROPs and 1536 shading units process the game’s 2D-style graphics with ease at 1080p, where the Ultra preset still hits 103 FPS. The boost clock of 1770 MHz and FP32 performance of 5.437 TFLOPS are the key specs driving these results.

At 4K, the GPU’s limits are exposed. The 84.96 GPixel/s pixel rate means the GPU can only fill about 85 million pixels per second, and 4K (3840x2160) requires over 8.3 million pixels per frame. At 49 FPS High, the GPU is nearly maxed out, and Ultra drops to 46 FPS. The VRAM capacity of 6 GB is not the issue here, as Inside is not a memory-heavy title, but the bandwidth of 288.0 GB/s becomes a bottleneck when texture filtering and fillrate demands increase at higher resolutions. The PassMark G3D score of 12871 and 3DMark Steel Nomad score of 1061 confirm that the GTX 1660 Ti is a mid-range part, ranking in the 41st percentile among all GPUs.

The GPU’s nearest rivals in benchmark scores are the AMD Radeon 540 (0.7% faster), AMD Radeon Pro WX 3100 (1.9% slower), and AMD Radeon R7 250 (2.2% slower). This places the GTX 1660 Ti in a narrow performance band, but in Inside, the measured FPS shows it is capable of 216 FPS at 1080p Low. The GPU’s memory clock of 1500 MHz (12 Gbps effective) provides enough bandwidth for Medium settings at 1440p, where it averages 124 FPS with a minimum of 106 FPS. The 169.9 GTexel/s texture rate also helps with the game’s detailed sprite work, but the GPU’s lack of ray tracing cores is irrelevant for this title.

The GTX 1660 Ti’s role is to render frames, and the data shows it does so effectively up to 1440p. At 4K, the user must drop to Low settings to maintain 98 FPS, which is a 51% reduction from 1080p Low. The GPU’s 120 W TDP and 300 W suggested PSU are modest, but the performance per watt is not the focus here. The key takeaway is that the GPU is the limiting component at 4K, while the CPU has no measurable impact on the FPS results. The 6 GB VRAM is sufficient for the highest preset at 1080p (103 FPS), so memory capacity is not a concern in Inside.

FAQ

*Q: What is the best resolution for this CPU-GPU combo in Inside?*

A: Based on the measured FPS, 2560x1440 at High settings provides the best balance with 78 FPS average. At 1080p, the frame rates exceed 100 FPS on all presets, but 1440p offers higher visual fidelity while staying above 60 FPS. 4K requires Low settings to reach 98 FPS, which is playable but sacrifices detail.

Q: Why does the FPS drop so much from 1080p to 4K?

A: The GTX 1660 Ti’s pixel rate of 84.96 GPixel/s is the constraint. At 4K, the GPU must render four times as many pixels as 1080p, and the measured 55% drop in average FPS across all settings indicates the GPU’s fillrate and memory bandwidth (288.0 GB/s) are saturated. The CPU’s performance is not a factor, as it has ample headroom.

Q: Does the Ryzen 9 9900X3D bottleneck the GTX 1660 Ti?

A: No. The CPU’s single-thread score of 3041 in Geekbench and 6739 in Cinebench R23 are far above what Inside requires. At 1080p Low, the combo reaches 216 FPS, which is likely near the game’s engine limit. The CPU’s 24 threads are underutilized, but the high boost clock of 5.50 GHz ensures the GPU is always fed.

Q: Can I play at 4K Ultra with this setup?

A: Yes, but at 46 FPS average, which is below the 60 FPS threshold for smooth gameplay. The Ultra preset at 4K is the most demanding configuration measured, and the GTX 1660 Ti’s 5.437 TFLOPS FP32 performance is insufficient for consistent high frame rates. Lowering to Medium raises the average to 78 FPS.

Q: How does the GTX 1660 Ti compare to its closest rivals in this game?

A: The GTX 1660 Ti’s average benchmark score of 7723 is 0.7% slower than the AMD Radeon 540, but 1.9% faster than the AMD Radeon Pro WX 3100 and 2.2% faster than the AMD Radeon R7 250. In Inside, these small differences translate to a few FPS at most, so the measured results are representative of its class.

*Q: Is 6 GB of VRAM enough for Inside?*

A: Yes. The game is a 2D puzzle platformer with limited texture complexity, and the measured FPS at Ultra settings (103 FPS at 1080p) shows no memory-related stuttering. The 6 GB capacity is more than sufficient, and the bottleneck is the GPU’s compute and fillrate, not VRAM size.

Measured FPS Breakdown

At 1920x1080, the GTX 1660 Ti delivers excellent performance. Low settings average 216 FPS, Medium averages 173 FPS with a minimum of 147 and maximum of 199, High averages 108 FPS, and Ultra averages 103 FPS. The difference between High and Ultra is only 5 FPS, suggesting that Ultra adds effects that are not demanding on the GPU. The 1080p results are all well above 60 FPS, making this resolution ideal for high-refresh-rate monitors, though the CPU’s single-thread strength allows the GPU to reach its limits.

At 2560x1440, the frame rates remain playable but show the GPU’s strain. Low averages 155 FPS, Medium averages 124 FPS (min 106, max 143), High averages 78 FPS, and Ultra averages 74 FPS. The gap between High and Ultra narrows to 4 FPS, but the drop from Medium to High is 46 FPS, indicating that High settings introduce a significant shader load. The 1440p Medium result is the best balance of quality and speed, with a minimum above 100 FPS.

At 3840x2160, the GTX 1660 Ti is clearly the limiting factor. Low averages 98 FPS, Medium averages 78 FPS (min 66, max 90), High averages 49 FPS, and Ultra averages 46 FPS. The gap between High and Ultra is just 3 FPS, meaning the GPU is fully saturated. The Medium preset’s minimum of 66 FPS shows that even at 4K, playable frame rates are possible, but High and Ultra are best avoided. The data shows a consistent pattern: each resolution step down (from 4K to 1440p to 1080p) roughly doubles the frame rate at the same settings, confirming the pixel-bound nature of the workload.

Settings Recommendations

For the best experience measured, the Medium preset at 2560x1440 is the standout choice. It delivers 124 FPS average with a 106 FPS minimum, ensuring smooth gameplay without sacrificing too much visual detail. The jump to High at 1440p costs 46 FPS (37% reduction), which is not worth the minor visual improvements in a game like Inside. At 1080p, Medium is also ideal, offering 173 FPS average, which is 65 FPS higher than High and 70 FPS higher than Ultra.

For users prioritizing maximum fidelity, Ultra at 1080p is the only viable option, as it hits 103 FPS. At 1440p, Ultra drops to 74 FPS, which is still playable but not as smooth as Medium. At 4K, only Low settings are recommended, as they achieve 98 FPS. Medium at 4K is acceptable at 78 FPS, but High and Ultra fall below 50 FPS, making them unsuitable for consistent frame pacing. The data suggests that the GTX 1660 Ti should be paired with Medium settings for a balanced experience, and resolution should be prioritized over preset level when moving to 4K.

The optimal configuration is 1440p Medium, as it provides a 124 FPS average with a 106 FPS floor, which is above the 60 FPS target. This combo leverages the CPU’s headroom while staying within the GPU’s fillrate and bandwidth limits. For 4K, Low settings are the only way to get close to 100 FPS, but users who prefer visual quality over speed can use Medium at 78 FPS. The measured rows show no benefit to High over Medium at 4K (49 vs 78 FPS), so High should be skipped entirely at that resolution.
