UMA frame buffer size, HELP?

Question

I mostly just use this comp to play a game called World of Warcraft. I've been checking arounf the bios settings and found a setting called UMA frame buffer size. I believe it can go to 32mb-1024mb. But it is currently on Auto. Would changing this to a high setting be any good for smoother gameplay?

Tyvm, I really need the info

Answer 1

The UMA frame buffer is, basically, the amount of RAM which is allocated to the graphics card. Your graphics card has around 1GB of dedicated memory, which is more than enough. You will not see a performance increase by having a large UMA frame buffer, and, because RAM is much slower than dedicated memory, it may even cause a drop in performance. In this case, you should leave the UMA frame buffer as it is (and, depending on the size, consider reducing it).

Answer 3

Go to Toshiba customer service website and ask there (hope you have registered your system with them) if not then register it if it is less than 12 month old) you will find that it is fixed memory that can't be increased
