That is a good point. I don't have a copy of the game to test, but my guess is that losses from crossfire scaling going from 2 -> 3 and 3 -> 4 GPUs is resulting in the load per GPU being reduced. i.e.
2 GPUs 100% + 100% = 200% of single GPU performance
3 GPUs 90% + 90% + 90% = 270% of...
As someone who has done a SIGNIFICANT amount of time researching microstutter with crossifre (2, 3 and 4 GPUs) there are a few key points I would like to add to this discussion that may clear up a few things.
1) What most people call microstutter is really just a difference in render times from...
Sorry about that, let me clearly state the issue I am having.
When using eyefinity with crossfire and running any DX9 title I cannot get vsync to work properly. There is tearing (not due to mixing dvi and displayport) and the frame rate is capped at 120 (2 GPUs) or 168 (3 GPUs). Eliminating...
Sorry for the really late reply on this one. I tested your fix and it works great when using the additional monitors in extended desktop mode. I am still having trouble with eyefinity +crossfire though. Windows sees the entire array as display #1 and CCC shows all three. Have you tried...
One more thing. I picked up 2 additional Dell 24'' monitor to play around with eyefinity, and can confirm that this bug also shows up while using eyefinity. This might explain the large number of reports of crossfire performing like crap with eyefinity.
Just an update on my issue. It looks like I am definitely losing v-sync with crossfire enabled and a second monitor attached, but only in DX9 games! I am getting the same bug as a few other people have reported where enabling a second monitor with crossfire causes the frame rate to be capped at...
After searching around the web, I have a new theory that I am going to test out tonight. I have found a few threads that seem to indicate that V-sync is being disabled while running an extended display and crossfire. It also turns out that Mass Effect 2 is frame capped at 62 so I wouldn't know...
I tried it with different connectors at first, Displayport on the 24'' and DVI on the 30''. But then I switched to DVI on both and still had the problem.
Actually, I played around with it some more last night and it looks like I forgot to include a crucial detail. When I was initially testing, I had both monitors running simultaneously and was just changing the primary. When I disconnected the 30'' and just played on the 24'' everything became...
You are correct. I ran them both at native. FRAPS was showing 60-62 rock solid on both displays in Mass Effect, but the 24'' was noticeably jerky. I even turned FRAPS off just to make sure that wasn't screwing something up.
Original Post: I have been gaming on my 3008wfp for over a year now and recently decided to pick up a 2408wfp for a second monitor. I decided to try a few games on the 24'' just to see how it handled them, and noticed that the frame rate seemed very jerky. I decided to try with crossfire...
I thought about that, but then i've got an 11 drive RAID 0 which is scary as hell. Also, I think I would have to add 2 additional drives to get it back to a RAID 6, since as far as I know capacity must at least stay the same.
Hi, first post here. I just did a capacity expansion on my Rocketraid 3560, and accidently set it to migrate my RAID 6 to a RAID 0. Does anybody know if there is a way to cancel this operation? Moving the data off and rebuilding from scratch really isn't an option because I have around 14+ TB of...
