So couple of years ago, using system ram as VRAM was a bad idea as it would cause slowdowns and stuttering. But on the other hand with more recent ram, there aren't any major slowdowns even if you use system RAM at least from what I've seen. I noticed this with the recently released rise of the tomb raider, a guy was using a 980ti to play at 4k with all settings cranked up and the vram usage was pretty much reaching 100% which required the system to use system ram instead (this was observable as at 4k he was using 10gb ram while at 1080p only 6gb was being used) and suprisingly no slowdowns were visible (framerate at 4k was pretty much what a 980ti is capable of)
So what's your opinion on this? I do realise VRAM is normally much faster than the ram that we buy for our systems but watching these videos did create some major doubts tbh.
Here's the videos btw
