I've had this HD 4670 (1GB) for a while now and it's never given me any problems that I can remember. However, when I did a dxdiag I noticed that it was only picking up 756 MB of vram.
Recently I upgraded my horrifically outdated computer to a more modern one. Along with that I've also upgraded from a 32-bit OS to 64-bit. In addition, the video card's driver was replaced with a 64-bit version.
One thing I've noticed is that Win 7 automatically installed DX11 and my video card only supports DX10. It's hard to tell if the lost memory has affected game performance (I've been playing games like Mass Effect 2, Skyrim, and Arma on a P4, so the I've only seen a drastic improvement over my old computer!).
I have three questions:
- Why is dxdiag only picking up 756MB of vram when the card really has 1GB?
- Is running a version of DirectX higher than your video card supports a bad thing?
- Should I be concerned with the loss of video memory and using an unsupported DirectX version?
My system specs are:
Core i7 930 @ 2.8 Ghz
Sapphire Radeon HD 4670 (1GB GDDR3)
8GB of RAM (Corsair Vengeance)
500GB HDD, Western Digital 7200rpm
Win 7 Ultimate 64-bit
Thanks in advance.
