Ok so i know the majority of the people on this forum use game cards. But I have recently just purchased the ATI V7800. Ive been having some display port issues with Maya 2011. Now I havent run any viewport benchmarks.

But Ive run into a couple other people with the same problem. I have been doing some research and some calls to tech support.

The drivers which I have seem to be running. But Ive been checking dxdiag in the OS and it seems to be reporting a total of only 996 mb of memory on the card. No matter which of the 4 diffferent drivers I have used it always seems to show the same thing. (BTW what is dxdiag and is that info accurate?)

I have heard that this does not happen when the card is installed on a 32 bit OS. I have win ult 64bit. I also have been monitoring the card usage during both maya modeling and gaming. During gaming the card shows 50-75% usage. But during Maya modeling with some complex and simple scenes, I get no increase in card usage. it stays near 0% or very rarely will spike to like 10%.

I also had an issue with the card not increasing core clock speed or memory clock spd under utilization. I have changed my power profile to high performance. Which has allowed the card to run at stock clock settings more often now.

But GPUz is reporting 2gb, Dxdiag is still reporting 996mb. Tech support was useless. Can anyone please help me along with some feedback here. Currently Im using the Maya certified driver. And Im still getting some poor viewport performance. This is my sig rig, btw. All tests done both at stock settings and overclocked.

And by performance issues I mainly mean very low fps when moving through the scene. This is with complex and simple scenes. The fps increases when Im zoomed into an object and less polygons are on the screen. This rig setup is a screamer when rendering though. So much faster at rendering super complex scenes than my previous setup.

Previous setup was a QuadroFX 3450. Q6600. 4gb ocz ram all stock. This setup had absolutely no problems with fps in the viewport with the same scenes.

Thanks all in advance.
