Is it better to use more or less VRAM?
The higher the resolution of the image you're attempting to render, the more vRAM required. … More vRAM means the GPU can hold and ultimately render more complex images and textures on the graphics chip, resulting in faster performance.
Is it bad to use all your VRAM?
Given game needs (and uses) only certain amount of vram at given resolution/settings. If that amount is less then GPU's vram that's ok. If that amount is higher then GPU'd vram then you run into trouble – namely lots of stuttering. Simply put, as long as it is below 100% there is nothing to worry.
What happens if you have less VRAM?
When and if you happen run out of video memory, then your PC will have to constantly jerk textures between main memory and video memory, which causes massive slowdowns, generally to unplayable levels.
Does less VRAM usage mean more FPS?
VRAM capacity is one of the least important aspects of a graphics setup. So long as you have enough of it to not bottle-neck you into around 10FPS or lower, it usually doesn't impact your gaming experience.
How much VRAM should I be using?
Answer: In 2021, 4 GB of dedicated VRAM should be the bare minimum to aim for in graphics cards. However, 8 GB is now the standard for most GPUs and that's what you should aim for if you want a future-proof graphics card and/or if you intend on getting a 1440p or 4K monitor.
