Vista and Catalyst 7.12, got some strange Crysis issues?! - 2008/01/14 12:33 I have two Sapphire Radeon HD 3870's in CrossFire with a Core 2 Quad Q6600 and I'm having trouble with Crysis. I'm on Vista 64-bit and if I go to the game explorer right click on the Crysis executable and launch the game in DirectX 9.0 I have no problems. The game is silk smooth with everything high with both cards working great. Now I was playing the game on very high DirectX 10 using the regular executable and in the beginning of the game both cards work perfectly until I get to first light then the frame rate drops like crazy.

I tried the same spot with one card and it was playable. So I thought maybe its a very high on DirectX 10 problem so I tested everything high using the same DirectX 10 executable and the same problem happens frame rate drops like crazy when I get to first light wondering if any of you are having the same problem. I'm using the latest Crysis patch 1.1. The problem is one card goes into 2D mode at this part is there a way to force both cards to stay in 3D mode?

Re:Vista and Catalyst 7.12, got some strange Crysis issues?! - 2008/01/14 18:45 Mmm, strange thing you are getting there... Well I can't really reproduce it as we don't have a Radeon HD 3870, and certainly not two. The only thing we could try is by using our GeForce 8800 Ultra but I don't think that will really worth it as it is not using the same drivers nor the same hardware...

Thanks for your response its very annoying I hope it will be fixed in the next driver version. I also saw on the AMD forums some talks about the same issue. Seems to be a problem linked to cycle syncro...

Well I removed the link as AMD we only allow certain links due to the fact that AMD is not paying us to direct people to their site. But I have gone through it and it seems an issue related to some syncro of the two cards and that when the GPU is dropping too much one card will drop down to 2D mode, as the PowerPlay feature dictates and therefore stuttering is happening. And well normally once the GPU activity is higher again it should go back to 3D mode... This is really something that AMD should fix for the CrossFire setups.

Re:Vista and Catalyst 7.12, got some strange Crysis issues?! - 2008/01/17 18:15 Just wondering are there any Radeon HD 3870 BIOS's on this site that keep clocks in 3D the whole time? As that I would like to try...

Sorry, but I can't answer really to that as these BIOS all have four settings with one of the them being the 3D mode and well I just don't have the time to go an look at each one of them to check that. I know that some OC versions have several of the four settinsg set equally but I doubt if all are the same. And still then it is confirmed that the PowerPlay reduced the clock speeds when just being in a 2D environment...
