Second GPU Not Being Used

[Superpatsy]

Hi all,

I've not been on my PC in about a month or so but finally managed to get some time on it last night and it seems as though an issue has cropped up...

I've noticed that when I was playing a few games last night that my second GPU was sitting at about 25C and the usage was fluctuating (like it would). This is the issue, my second 280X has never been that low a temp in game before.

Afterburner is saying that the card never topped 30C and was at 100% usage but when I was playing games, the performance was as if it was only running on one card. I checked in CCC and Xfire was enabled and overdrive was enabled for the fan speeds.

Any suggestions as to what could be causing this, and a fix?

Apologies if that doesn't make a great deal of sense. I'm running off little sleep and a mild concussion!

Cheers!

Not running in windowed mode and ULPS is disabled. I'll try the rest later when I get home from work!

Tried everything above now and the issue is still there. ULPS is disabled, running full-screen mode, un-installed/re-installed drivers.

I checked CCC when I was playing a game and it appears as though the second card isn't kicking in at all even though in AB it saying that the card is being used.

Attached a few screens to show what the issue is.

The Alt+Enter has worked in Sniper Elite 3 and DA: Inquisition. Was going to try it with BF4 but the game keeps freezing....

Tried it with Enemy Front and it still not working.

Use after burner the. Do a run of 3dmark to see if there is anthing going on the fan is at 60% so it as to be doing somthing

I set the fan speeds manually.

Did a quick run and the second card is kicking in now.

It appears as though there's a few games that it doesn't like working in...

Seeing as the alt+enter is working with some games and not others, could it be driver related?

Is there an actual fix for this because having to alt+enter is a bit of a pain in the backside?

 

[Superpatsy]

It would appear that games are not running in full screen, because all Alt+Enter does is switch a game from full screen to windowed mode. Assuming you've followed my instructions from earlier to try a fresh install, then i would definitely look at trying an older set of drivers - just to rule it out.

The games are definitely running in full screen. I'll try and older set of drivers later on. I'd like to leave the fresh install until last...



Also, any word on VSR on my GCN architecture?

Progress appears to have been made and I'm back to fully functional! (Other than the horrendous load times on Advanced Warfare...)

Thank you all very much for your help!

 

[Superpatsy]

Good to hear.

What fixed it?

The alt+enter worked for majority of them but some games weren't letting me alt+enter during the game, but would allow me to do it when the splash screens were running. Frustration was starting to set in when I was trying to get Enemy Front working so I just kept mashing alt+enter from the second I ran the game and it worked!

Don't need to do it every time I run a game. Do it once and it'll keep the 'settings' the next time I run it as well.

Thanks again!

Now I can't get the 3D clocks to kick in with Far Cry 4...

That's because as of yet, there's no Crossfire profile for that game. It will be added, once we've fully tested that it's safe to do so with our profile. Due to issues with the game, we had to disable the profile while issues with fixed by the developer.

However you can get it working in the meantime by using a custom profile and AFR friendly within Catalyst Control Center.

Do you happen to have an ETA on that?
