How to fix VRAM bandwidth issues on Colorful GT 1030 in CS2?
Whenever a smoke grenade pops, my frame rate feels like a roller coaster, swinging from 60 down to 20 FPS—absolutely ridiculous. The 2GB of VRAM on the Colorful GT 1030 just hits a wall, leaving the GPU idling for 30-50ms while waiting for data. I tried the 'High Performance' power plan, but the card just shot up to 82℃ without fixing the lag, which was just pathetic. I finally updated to the latest drivers, switched the render API to the most compatible mode, and killed all dynamic shadows. In 3DMark, VRAM usage stayed around 1.8-1.9GB, and the FPS finally settled into a 45-55 range. I dealt with some screen tearing after the first tweak, but enabling half-rate V-Sync fixed it. Core temps stayed between 65-72℃. I exported the render parameters to a config file so I don't have to do this again. It's a low-end card, so don't expect miracles, but it's stable now.
