Hello, I understand the model isn't the latest. Your XPS 9500's GPU runs at 40W for roughly three minutes before it throttles down to 20W and drops its frequency to around 1400MHz instead of the usual 1900MHz. After throttling, utilization hits 100%. It looks like Dell has set a long-term power cap of 20W for this model. Can you try to find a way around that limit? It really affects performance, dropping from about 60 FPS at 50% usage to 30 FPS when fully utilized. Before throttling the temperature was 75°C, then it fell to around 65°C—seems not high enough to trigger the cooling reduction. After throttling: it appears this issue is linked to Dell.

It appears your GPU memory usage is quite limited during throttling, which could indicate an issue.

The GPU memory clock appears to be the issue. I lowered my GPU speed to 1500MHz with MSI Afterburner, and the game runs smoothly. Still, throttling occurs. The best solution seems to be further reducing the GPU speed so it stays under 20W even when the game is demanding.
