Video Memory Stress Test (VMST) is an excellent diagnostic program created to check how stable and dependable your computer’s video memory is. This tool has become popular because it can put heavy load on the graphics memory system through various methods like rendering in high resolution, running complex shader calculations, and loading numerous textures. The software works by pushing your graphics card’s memory to its limits, which helps identify any defects or issues that might lead to system crashes or visual glitches during regular use.
