Question Need help fixing allocation/reallocation issues

[cos_ine]

I had problems with Rust crashing, and when I contacted support for the second time and sent them my DxDiag file and the game's output_log.txt, this was the response that I have gotten.

Your log is showing a lot of errors from your graphics card memory, this could either be with the GPU's own memory which would suggest it may be faulty or the 8GB of your RAM that windows is sharing with it is not being allocated/reallocated correctly

Does anyone have an idea on how to fix the incorrect allocating/reallocating?
