| Post subject: | HD7950 stuck at 30 fps after intense graphical scene |
I always play games with v-sync turned on (love the smoothness). For a while now games seem to stutter after intense graphical scenes. I turned fraps on and noticed that sometimes the frame rate was stuck at 30 fps. It seems that after a taxing moment fps drops as normal, but the driver (or something else?) doesn’t let the frame rate return to 60 fps when the taxing moment is over. I have noticed this behavior in BF3, MW3, Saints Row 3 and Max Payne 3 (wow, lot of threes.. ;) ), but not in League of Legends (probably because it isn’t taxing at all. Things I tried, but didn’t change anything: - Install new drivers (am on 8.98-120604a, aka 12.6 beta) - Turn off all overclocks (actually made the problem worse since fps dropped more often) - Turned off Powerplay, so clocks remained fixed - Turned off Microsoft Security essentials - Updated mb bios (although not to solve this problem) Ways to "solve" it: - Turn v-sync off (fps returns to normal values even if it was stuck at 30 fps) - Lower graphical setting so the fps won’t drop way down around 30 fps and get stuck there - Restart the game every time the fps gets stuck The above three solutions aren’t satisficing at all. I have three questions: 1. Do you guys also experience this problem? 2. Would you guys agree that switching to a gtx 670 (CUII top), would solve this problem, because of adaptive v-sync? 3. Is there any change a clean win7 install would solve this problem? |

| Post subject: | Hello Wijkert,Never |
Hello Wijkert, Never experienced something like it but i have a two GTX 560TI's so i think its ATI's driver or card. If i where you i would switch to Nvidia because i never have problems with it and i once had a low fps problem with my hd 7970 but at the end i returned the card for two GTX 560TI's and the problem was resolved. It may help to reinstall windows but if this problem has just come up i would go back in time (before the problem) and see of that helps. Or maby you have a back-up of your computer who can be restored if this problem has just come up. You can always try to reinstall windows if you don't have important stuff on your computer to see if that resolves the problem. Hope i helped you! :bigsmile: Sh4dowking |

Try D3DOverrider, it will force tripple buffering in all you games so you wont get tearing (with v-synch) and you get every frame rate you deserve (aka 31-59 become available again). |

Just me wondering, but when you use Afterburner FramerateLimiter and set to 60FPS. Does that behave same like Vsync? |

| Post subject: | First of all, thanks for the |
First of all, thanks for the posts. Second of all, I have seem to have solved this problem by rolling back to 12.4. Normally this is one of the first thinks I try when such an issue arises, but I was convinced that the problem was present when I had 12.4 running. Looking back, that probably wasn’t the case. When updating the drivers I didn’t go from 12.4 to 12.6, but from 12.6 to a different 12.6 :( My current hypothesis is that this bug has something to do with no longer having tearing when using three different monitor inputs (dvi, dvi and dp in my case), since tearing normally removed by turning on v-sync and I had a v-sync problem. I hope that this gets resolved with either the 12.6 (whql) or the 12.7 beta release. |

| Post subject: | Although the above solution |
Although the above solution works (rolling back to 12.4), I would like to be able to use 12.6/12.7, because of the performance boosts and no more tearing on monitors that are connected differently (e.g. dvi when main display is dp). In the meantime I have reinstalled windows (because of a different reason) but that didn’t change anything. Maybe you guys know of some more things I can try out to solve this? Is there anyone here who has the same problem as me? |

| Post subject: | Installing 12.8 WHQL didn’t |
Installing 12.8 WHQL didn’t help. If any of you guys can confirm that you have similar problems with either 12.6, 12.7 or 12.8 it would help, since I can at least stop searching for an solution and be patient until AMD solves this problem (probably not high on their to do list, but still). |

Where as a frame limiter will just do that, limit the frame rate to what you set it to. Tearing can happen at any frame rate, it's just less noticeable when you are running a lower frame rate that the refresh of a monitor. This is because the difference between one frame and the next frame will be smaller than if it were a higher frame rate. Triple Buffering allows the drawn frames to be pushed into buffers before being sent to the monitor. This allows the monitor to always have a frame to get at each refresh cycle. So it doesn't cut your frame rate. The only con you get is introducing a minute amount of lag. It's an extremely small amount of lag, but some people still feel it. |

Just to add, I think I am having this issue too. Thought I was going crazy, even stuff as old as HL2 gets capped at 30fps (and drops lower) with VSync on but soars to 125fps with it off. Thats not right! Im using 12.8 and sick of swapping drivers for now so I will just leave it off. I might try D3D Overrider too. |
