Fixing VRAM latency on Manli RTX 5070 in Helldivers 2
The second an orbital strike hits, the game freezes for about 0.2 seconds. It's like playing a slideshow in the middle of a warzone, which is just ridiculous. The GDDR7 memory on the Manli RTX 5070 was struggling with massive particle effects, and due to some janky driver cache allocation, the addressing latency was jumping between 12ms - 20ms. I tried dropping the resolution from 4K to 2K, but the stutters were still there—just with a higher average FPS. That was a total waste of time. I went into the NVIDIA Control Panel, manually set the shader cache to 10GB, and did a clean install of the latest Game Ready drivers. My frame time analyzer showed the spikes dropping from 15ms - 35ms to a stable 8ms - 14ms. I noticed some textures loading slowly at first, but bumping the Windows page file to 32GB fixed that right up. VRAM temps are hovering around 68°C - 75°C, which is acceptable. Exported the logs and confirmed the fans are steady at 1400 - 1600 RPM.
