How to fix resource scheduling on Colorful iGame RTX 5080?
Whenever I'm hitting fast slides or jumps, the screen just hitches for a split second. It's a total nightmare when you're pushing 240 FPS. I dug into the logs and found the GDDR7 memory on my Colorful RTX 5080 was hitting response latency spikes of 14-22ms around 28Gbps, which completely trashes the frame pacing. At first, I tried the 'Prefer Maximum Performance' toggle in the NVIDIA Control Panel; it bumped my average FPS by maybe 5, but the stutters actually got worse, which was beyond frustrating. I eventually went into the tuning software and manually set the core voltage offset to +0.03V and pushed the power limit from 400W to 450W to stop the clock from dipping during transient peaks. Running 3DMark stress tests, the core frequency finally locked in between 2.5-2.7GHz, and the frame time variance tightened from a messy 7-20ms down to a steady 5-12ms. I actually bricked my driver once by being too aggressive with the overclock, and I had to back off the memory clock by 100MHz to get it rock steady. Core temps are sitting at 64-70℃, while the VRAM is between 78-84℃. I saved these specific voltage parameters to a profile, and now my frame times are a consistent 5.1-6.4ms. It's a relief, though the power draw is definitely higher.
