How to fix VRAM spikes on Vastarmor RX 9070 XT in Primal Carnage?
This card is an absolute power hog, and it's honestly hilarious that a high-end beast like this can max out its VRAM in a remake of an old game like Primal Carnage. VRAM usage was hovering between 15.2-15.8GB, and every time the resource recovery kicked in, my FPS plummeted from 160 down to 30. It was like a joke. I tried dropping textures to Medium, but the game looked like a pixelated mess, so that was a hard no. I used a memory profiling tool to force-expand the game's texture pool cache and disabled Windows virtual VRAM mapping. In GPU-Z, the memory clock finally stayed at its peak without those sudden resource-recovery freezes. I had a rough start where the game crashed three times during the cache tweak, but increasing my page file to 32GB stabilized it. Temps are 65-72℃ with fans at 1800 RPM. I exported the peak VRAM logs for verification, and fans stayed steady between 1750-1850 RPM.
