AMD Catalyst 12.7 Beta

[broken pixel]

I'm currently using 12.6 and get horrid FPS in Clod.
I have more than enough video memory and system memory.
I am using a 6990 + 6970 in trifire and my frames are in the 30s
& 40s

I have tried the DX10 lost planet profile in CCC but get constant flickering when enabling the profile.

I'm about to try out the 12.7 betas with the 12.7 CAP profile.

I get better frame rate with the 12.7s but any crossfire profile I use renders
bad flickering.

I had the same issue - I also tried the Lost Planet DX9 and DX11 profiles. Try playing with the Vsync settings - turned off in CLOD and "wait for vertical refresh" in CCC. I am still experimenting myself

Could be your linked cards are different?? I have two identical cards linked with Crossfire.

A 6990 is basically two 6970s so I have 3x 6970s.

I posted this over @ sim HQ.

I was using the 12.7 beta drivers and it was really choppy at times and I would get huge drops in my fps.
I switched back to the AMD Catalyst 8.97 18 April drivers and a lot of the stuttering has gone away.
These drivers from the benchmarks this guy does scores the highest of all the AMD drivers to date.

I made a track and got hit in the engine early in one of the quick missions. My engine caught on fire so I had to fly towards land.
I notice my GPU usage was in the 20- 50% range during game play with vsync.
I then decided to play my track of the engine fire while tweaking settings.
The weird thing is during that track I was getting 60- 97% usage with multiple profiles settings I made. I play other tracks and my GPU usage is crap. I will only see the 60- 97% when I play my engine fire track.

I'm stumped? The 8.97 18 drivers seem to help a lot with hiccups and stutters during game play with vsync on & HT disabled in the BIOS.

Time for a few hours of sleep, then it's back to the drawing board.
