Stabilizing frame rates for Colorful RTX 5080 Ultra in CS2
Right as I went for a precision headshot, I'd get these anxiety-inducing micro-stutters where the minimum FPS would tank to 140. The core clock on the Colorful RTX 5080 Ultra was bouncing wildly around 2.6GHz, causing frame times to jump between 4ms and 12ms. I tried disabling all hardware acceleration in Windows, which gave me a pathetic 5 FPS boost but didn't stop the spikes—it was a frustrating waste of effort. I eventually used the OC software to cap the power limit at 90% instead of 100% and set a custom fan curve to hit 80% speed at 60℃. RivaTuner showed the frame times finally settling into a rock-steady 5-7ms window, and that flick-shot smoothness finally came back. The fan noise was deafening at first, but I dialed back the 80℃+ speeds to 90% to find a balance between noise and thermals. GPU temps stayed at 62-68℃ and VRAM at 75-81℃. Stress tests confirm the frequency is no longer jumping; the setup is solid.
