I recently got a Sapphire 6950 and I've been having problems with screen flickering. It occurs when I am watching anything on vlc or media player classic and during in game videos. It doesn't occur during actually playing game though. I tried using my onboard graphics and the same problem occured in vlc. It didn't happen before when it was just the onboard graphics I had. Anyone got any ideas?
V-Sync?
It limits your card to 60FPS (or whatever your screen refresh rate is) to avoid flickering and "tearing" in videos and games.
There are no settings for v-sync when watching videos as far as I can see. It's not so much flashing but noticeable stuttering when the action is fast moving in game menus, videos and in game cut sequences. I tried removing old amd drivers with driver sweeper and re-installing but it's still there.
I'm wondering if it has anything to do with the fact that I need a 5m hdmi cable to reach my Samsung tv. Probably shouldn't use one that long I'd have thought but if it was that I'd notice the stutter elsewhere. Could it be ram or instability in my i5 overclock?
Real time or recorded cut scenes? sometimes it's the little things, have you considered codec issues?
The problems are real time. Both in menu's and cut scenes. Have tried clearing cmos settings, re-seating ram and gpu and checking all connections. Which codecs would I have that would cause a stutter in vlc and in the dirt2 opening credits?
I did try to flash the bios in my 6950 to a 6970 and it didn't work. Thought it may have been that but I'm sure the original bios has been restored and it wouldn't make a difference when I switch to onboard graphics surely.
The rest of my PC in case that helps is:
Asus p8z68-v/gen3
2x4GB Corsair XMS3 ddr3 1333
XFX Core Edition PRO 650W psu
Sapphire Radeon HD 6950
i5 2500k
Windows 7 Home Professional
Crucial m4 120GB
Samsung Spinpoint HD204UI 2TB
TV is a Samsung Series 5 37" LCD which is fine with Tivo box and ps3
It's really doing my head in. Thanks for the replies so far guys
No codec should cause stuttering in VLC....as it doesn't use codecs...everything is self-contained.
I would bite the bullet and re-install Windows....then check playback at every step of the way.
Why go that far straight away? download a linux live cd, and run a video file from that, if it stutters in a completely different os then it is a hardware issue and reinstalling windows will have no effect.
Well, because I expect the LiveCD to run fine.
From the OP.....it sounds like the problem started after installing a new gpu....but switching to on-board has not rectified it.....so doesn't sound like a driver issue.
He also states games run fine (it's only the videos).....so I doubt it's hardware.
So, you are left with a very fickle software trouble-shoot......probably something messed with during installation/de-installation of drivers.....or some bloat.
Thanks for the help guys. I done a system restore to the earliest point possible and it sorted it out. I had tried before but forgot to tick the "show other restore points" box. Now I have lots of un associated files from things like steam, various games and programs which I'd like to remove before a clean install of them all again. Anyone know the best way to get rid of these files or is it as straight forward as just deleting them?
