The scaling from 1080p to 4K shows a 62% reduction in FPS at Low settings, which is less than the 4x pixel count increase, indicating that the CPU continues to play a significant role even at higher resolutions. The processor's 4.70 GHz boost clock and 12 threads provide sufficient headroom for Roblox's workload, though the data suggests that frame rates above 700 FPS are constrained by CPU performance rather than GPU capabilities.

Settings Recommendations

The measured FPS data shows distinct trade-offs between visual quality and performance across the four settings presets tested. At 1080p, all presets deliver frame rates above 500 FPS, with Low at 776 FPS, Medium at 706 FPS, High at 625 FPS, and Ultra at 507 FPS. The difference between Low and Ultra at 1080p is 35%, which is notable but still leaves Ultra at a very playable frame rate. Given that even the most demanding preset at the lowest resolution produces over 500 FPS, the Ultra preset at 1080p represents the best balance for users with high-refresh-rate displays.

At 1440p, the pattern continues with all presets exceeding 330 FPS. Low delivers 518 FPS, Medium 471 FPS, High 417 FPS, and Ultra 338 FPS. The 35% reduction from Low to Ultra at this resolution mirrors the 1080p scaling, and the Ultra preset remains well above any practical refresh rate limit. For users seeking maximum visual fidelity without sacrificing performance, Ultra at 1440p is the recommended configuration, as the 338 FPS average still exceeds the capabilities of most displays.

At 4K, the presets show more differentiation: Low produces 293 FPS, Medium 267 FPS, High 236 FPS, and Ultra 191 FPS. The Ultra preset at 4K delivers the lowest measured performance in the dataset but still maintains 191 FPS, which is suitable for high-refresh-rate 4K displays. The Medium preset at 4K offers a 40% improvement over Ultra at 267 FPS, making it the recommended choice for users who prioritize higher frame rates while maintaining moderate visual quality. For users with 120 Hz or 144 Hz 4K displays, the High preset at 236 FPS provides a strong balance between visual fidelity and performance headroom.

In Roblox, the GPU's role varies significantly by resolution. At 1080p, the frame rates exceeding 500 FPS across all presets indicate that the GPU is not the primary constraint, as the card's massive compute and memory resources are underutilized at this resolution. The 32 GB VRAM allocation is far beyond Roblox's requirements, and the 1.79 TB/s bandwidth provides more than enough throughput for the game's texture and geometry data. The GPU's 92nd percentile ranking among all GPUs in synthetic benchmarks confirms its high performance class, though Roblox's relatively simple graphics workload means the card operates well below its theoretical maximum.

At 4K, the GPU becomes more relevant, with the 43% FPS reduction from 1440p indicating that the increased pixel count places additional demands on the rendering pipeline. The RTX 5090 D's boost clock of 2407 MHz and 104.8 TFLOPS of FP32 compute provide substantial headroom even at 4K Ultra, where the combo still delivers 191 FPS. The GPU's nearest rivals in synthetic benchmarks include the AMD Radeon RX 6650M XT with a 1.1% higher average score, the AMD Radeon RX 6850M XT with a 1.6% lower score, and NVIDIA Tesla P100 variants with 2.1% to 2.4% lower scores, placing the RTX 5090 D in a competitive mid-range position despite its high-end specifications.
