Frequently asked questions

What happens when VRAM runs out?
The driver spills data over the PCIe bus to system memory. Average FPS may barely move while frame times spike badly, which reads as stutter and pop-in textures.
Does upscaling save VRAM?
Yes. The game renders at a lower internal resolution, so every frame buffer shrinks — though texture memory stays the same.
