The AMD Driver Thread

Fixed the black screen before login, remove drivers reboot, run ddu reboot, install 15.8 reboot and should be back to normall, if running two or more card's, press windows key search regedit press ctrl+f , write EnableUlps, double click and change the value to 0 instead of 1, then reboot.
 
I've disabled ULPS, not because of the black screen issue (15.8 seemed to fix this) but because lots of programs which don't need a second GPU (Skype, Spotify etc) turn on the second card and the noise of the fan spinning up when this happens is annoying.

This only started happening since upgrading to Windows 10, and this is despite "Enable AMD CrossfireX for applications that have no associated application profile" being unticked.
 
I'm having trouble getting ULPS to actually work!

I'm running Windows 10 Pro with 7850s in Crossfire using the AMD 15.8 drivers.
ULPS is enabled in the registry and works for a while after loading Windows. This is easily confirmed using GPU-Z or similar, plus the fan on the second card does not spin. Randomly, some software will cause the second card to power up (2D clocks as per GPU-Z and Afterburner stats plus i can see the fan spinning).

This issue never happened in Windows 8.1, ULPS worked perfectly as it should despite everything being the same, bar the OS. I have now reinstalled Windows 10 many times, tried 15.7.1 and 15.8 etc. yet ULPS still decides to stop working randomly.

edit- In fact one of the main culprits for turning ULPS off on my system appears to an application called Windows Firewall Control by Binisoft which is just a front end for the Windows firewall. Often, shutting this application down will turn ULPS back on and the second card will power down again. strange. Other times, i have noticed that using Firefox will activate Crossfire. That didn't happen in 8.1.

Well thanks to reddit, seems there's a fair few Linux fixes in the 15.9's :cool:
Also leaked a game release due by the looks of it :p

I'll not post and let you do the honours Matt :p
 
It's been a year or so since I've had AMD cards, and I'm contemplating what to get for the Mrs' PC. Can anyone tell me if the following driver issues are fixed?

No refresh rate override: nVidia let you "force max refresh" meaning games with no refresh rate selection run at 144hz, and games like Crysis 1 that default to 24hz on a TV run at 60hz on the TV, etc.
No forced vsync in DX games: There was a CCC option last I checked but it only worked in OpenGL.
No Crossfire in windowed mode: Was quite a big issue for me as so many games use borderless windowed instead of fullscreen now.

Thanks!

AMD introduced Frame Rate Control so you can specify a maximum frame rate to limit games to, is this what you mean on point 1? It only goes up to 95FPS at the moment, and only works on DX10 and DX11 games, but it is a new option in the drivers so may improve in the future.

No forced Vsync in the drivers for DX games.

Crossfire still works only in Fullscreen for the majority of games (the only exception I know of is games running Mantle rather than DX, where I'm sure people mentioned it worked in Windowed mode too).

Not quite, although that sounds a nice feature. I mean the refresh rate of the display. When I first got a 144hz monitor I still had AMD cards and found that many games just ran at 60hz and didn't let you specify a refresh. Crysis was an example of a game that used to default to the lowest refresh the monitor supported (meaning 24hz on my TV). nVidia let you override this and always run at the max refresh of the screen, which I really like. She will be using my old 1080p144 monitor, so this would be nice.

The crysis issue was because of 1080p was seen wrong by the game so instead of it finding 1080p 60hz it would bug out and default to a safe setting. Sadly safe setting was 24hz

The known work around was to setup a custom resolution of 1920x1040 game would then use 60hz.

To answer your question about refresh rate, radeonpro has the force refresh rate. I used to use this for fifa 14 the only game I have had to force a refresh rate..

Sadly since they updated the fifa engine on pc 15 and 16 is now hard locked to 60hz.

So this is my advice not all games mostly older games support 120hz or 144hz and are locked to 60hz without anything you can do. Some allow you to by pass it but most the time it's hard locked.

Strangely enough though I have found some games that lock to 60fps do indeed run a 144hz metal gear solid 5 for example does this.
 
Fifa 15 and 16 (demo) are not hard locked, run both at 5k dsr 144hz no problem, both sit in the 120-140 fps region.

As for crysis, if my memory serves me well, you can force the game into borderless window full screen, it then forces the game to run at the same refresh as your desktop, though this does (or did?) Kill crossfire if you used it.
