Crossfire problem tombraider?

post #1 of 7
Thread Starter 
So I recently got a new crossfire setup. It works fine in other games like fsx and benchmarks fine in furmark, passmark, and valley. However, when I played tombraider, I noticed that the second gpu wasn't utilized at ALL. Then I downloaded AMD application thing for catalyst and the second gpu was used for the intro screen, however when I ran the benchmark GPU1 was at 80% while GPU2 was at 0%.

Setup -
4770k Stock
4 x 4 GB G.skill
7870 XT Sapphire
7870 Powercooler Myst
750 Watt Seasonic PSU
Asrock Extreme 6 Motherboard

Running at 5760x1080

IDLE
Sapphire XT - 45 C
Powercooler Myst - 31 C

LOAD - Valley Benchmark Extreme HD
Sapphire XT - 77C
Powercooler Myst - 68 C

That's odd I'm getting 98% on both cards maybe try installing the cap13.5 profiles I currently have them installed.

I'm running on 13.6. I'll downgrade and see if it does anything. I have the latest version of tomb raider too.

This is my benchmark score (Ultra*FXAA)

I use 7970 Crossfire with 13.6beta2 (but I do not install 13.5 cap and disable ULPS)

It performances very well , GPU1 and GPU2 were at 98%~99% .

1920*1200



2560*1440
