F**king Stutter problem

mim525 · March 30, 2014

I think the most recent patch may of caused this but, the game is just unplayable due to the excessive stuttering that is going on, awhile ago I never had this problem but now this new patch screwed things up. Anyway of going back to an earlier patch? OR even better has anyone encountered this problem and have a fix? Strangest thing is I switch my view to an ai plane and all is good no stutter. GPU is Asus ATI Radeon HD 6670 2GB running on windows 7 64bit. :(

need more info bud. what game, heavy modded or stock install, is it a particular area/aircraft/mission or all that cause it.

yes you can go back to a previous patch IF you saved your files before upgrading.

As I noticed, latest SF2 patch iteratio0ns have serious problems with AMD Graphic cards. Namely the issue is that you cannot turn off the V-Sync so users of recent AMD graphic cards are limited to 60 FPS. What is worse SF2 uses only Double Frame Buffering which means that as soon as the FPS drop below 60, they actually drop to 30 FPS.

So at one moment your enjoying 60 FPS then seconds later it drops to 30 FPS (because a missile or a flak exploded in your field of view, which normally would drop your fps to, say, 57 - but since your locked with double buffered V-Sync it drops to 30, hence the stuttering).

TL;DR - TK needs to publish another patch dealing with recent AMD GPUs and VSync.

yeah, that's the problem, stock or heavily modded. The only way i see this being fixed is if thirdwire decide to release a new patch, but are they aware of the problem? im sure they would of fixed it by now if they knew of it. damn this really is a pain the backside :blink:

i run a Radeon card (Win7, HD 7470 card, 8GB mem) and only have stutter when flying over Iceland in NA. true most say that SF2 and Radeon don't get along, but its not impossible.

the last patch was released last July, so something had to have happened elsewhere if the problem is recent.

and finally my two cents....... asking TK for another patch is as needed and wanted as a forced vasectomy!!! those that do mod this game have a serious love hate relationship with patches esp in finding what they break in mods and when he doesn't patch we can work around whats broke cause its known.

**Spinners** · March 30, 2014

I agree with daddyairplanes - stability is good!

mim525 - Hope you can get your stutter problems sorted mate.

mim525 · March 31, 2014

damn, are there any ini tweaks around that could if not remove the stutter make it a bit less noticeable

+**daddyairplanes** · March 31, 2014

when did 1. you first download a version of SF, 2. what version, and 3. how long ago did the stuttering start?

mim525 · April 4, 2014

Not long ago, have latest ofc :aggressive: . Still can't find a solution, as i said before when I switch my view to an ai plane all is good ,no stutter, Is there anyway in which i can fool the game to think im an ai plane ? As its only when i've switched my view to the aircraft i'm currently flying there is stutter and lag. Or perhaps its an audio problem which is causing this. There must be fix :baby:

I presume you're having this issue when in the cockpit.

If they're on, try switching off your cockpit mirrors in the graphics options. I've got an AMD graphics card and had the same problem. Straight away I noticed a huge improvement in the framerate.

mim525 · April 5, 2014

tried all that ,its when i'm viewing the plane from the outside as well where theres stutter not neccecarily lag but when i look at the terrain the fps is like 30 but the movement is all stuttery sort of like this

but in sf2 ofc

**MigBuster** · April 5, 2014

What patch did you move from to?

Have you tried tweaking graphics card settings? Are you using newer ATi drivers?

Can you post dxdiag.exe output?

mim525 · April 6, 2014

Not sure wth i did but i started up my computer and the game diddn't stutter at all, if i remember , correctly i diddnt have anything plugged into the audio jack, that was when the game started and i was flying with no lag so i put in headphones , everything worked, then i put in some other headphones and the lag was back again.. so i disconnected those headphones and now it still stutters. :angry: But what i have noticed is that when i put the sound setting to 8 channels it lags less than on 32.
