R9 270X CrossFire not working

URBAN303 · Sep 26, 2014

The last WHQL Driver is 14.4 (http://www2.ati.com/drivers/14-4-win7-win8-win8.1-64-dd-ccc-whql.exe)

The RC1 14.7 is not longer available on AMD Website so i upload it on my dropbox for sharing public link in few minutes

((about 5 minutes waiting))

If you don't use RAID System you can using "AMD Cleaning tools" for uninstall all Amd catalyst before reinstall new version ^^

I think I might wait it out for 14.7 stable. How long do you think it will be till 14.7 moves from beta to stable?

14.7 (14 = year of release // and 7 = month of release)) so the next WHQL or Stable version will be 14.10 for October or 14.11 for november (or 14.12 for december so!) i think

OK, thanks. I didn't know that's how their update system worked.

If you have multi monitors enabled disable it or format your machine and start fresh

I've thought about doing that. I don't obviously want to, but being the easiest (possibly only) way to fix it, I'll probably just suck it up.

Update 6: So, I recently rebuilt my rig into another case. After getting it set up, and doing some messing around, I noticed that when launching TR through a windowed instince of Steam, it opens in exclusive full screen. It seems to be then that using Big Picture Mode prevents TR from opening in exclusive full screen. I'm thinking about sending in a bug report. What do you guys think?

eidairaman1 · Oct 2, 2014

Report it to the game maker and AMD. Otherwise run it the way you discovered the fix.

So, I shouldn't report the bug to Steam? I know Big Picture is in beta, but still...

eidairaman1 · Oct 2, 2014

Report it to game development and Amd. You might even do it to steam but steam is like a download management tool

Steam Big Picture disables any Multi-GPU SLI or Crossfire. I understand this post is from a year ago, however it has not been resolved. Anyone have a work around?

No, but I also don't even own these cards anymore.
