How to handle VRAM spikes on Manli RTX 5070 in Overwatch 2?
Whenever a massive ultimate went off, my FPS would tank from 240 down to 85, and my anxiety just spiked. The RTX 5070 OC was hovering between 9.2-11.4GB of VRAM, but the bus was lagging by 14-22ms during peaks. I tried dropping the resolution to 2K, but the aliasing was so bad it was unbearable—definitely not the way to go. Instead, I nuked the NVIDIA shader cache folders and bumped the texture quality down from 'Ultra' to 'High'. In GPU-Z, the memory clock stayed locked at 2100-2250 MHz, and those annoying drops completely vanished. One heads-up: after clearing the cache, the first match was a stuttery mess for about 2 minutes while shaders recompiled. Now it's smooth. Temps are 64-69℃ and the fans are humming at 38-42 dB. The frame time graph is finally a flat line, and the mouse input feels instant again.
