Is there a way to lock the Frame Rate in Silent Hunter 4?

nx02nx02 · 02-28-08, 09:58 PM

I have a 8800GTX and in Silent Hunter 4 the frame rate jumps around so much it causes stuttering, non smooth graphics. Vsync only helps so much. because when the FPS drops below the vsync refresh rate the stuttering starts again.

I have my refresh rate at 100 and frame rates jump between 40 and 90 FPS on max settings. This causes terrain lag and graphics stutters. I just want to force the Frame Rate to stay at 40 and then it will stay smooth.

Is there a console command or a program that can lock the framerate?

I have tested it a bit more and I have my refresh rate at 100hz. So this locks the in game framerate to 100 FPS, as long as the ingame framerate stays at 100 it is perfectly smooth. If the ingame framerate drops to even 99 or 98 FPS = instant stutter and looks like it's at about 10 or 15 FPS.

Is there any way to fix this?

While playing games it's perfectly ok to set the refresh rate at 60 Hz (from the Graphics Options menu) and thus limiting the framerate at 60.

I have an 8800 GTX and I don't get any such problems when the fps drops below the vsync rate.

Ok I have been doing some testing and here is what happens. Playing the game with 1024x768 @100hz with vsync on. These settings lock the framerate at 100FPS. Using fraps and the ingame counter, (ctrl+F8) During certain times in the game the frame rate reads exactly 100 FPS and no fluctuating. as long as it stays right at 100 it is ""perfectly"" smooth. But the second it drops to anything but 100 even if it just drops to 99FPS or 98 FPS sometimes 95FPS or so = instant stutter, lag, frame rate stutter. It honestly looks like it's at about 5 or 10 FPS but it reads in the 90's. Then when it goes back up to exactly 100FPS, (where the refresh rate and vsync is) it instantly becomes smooth again.

When it dips to 98 or 95 or so the frame rate looks really low. I can see the slowness to the framerate. I shouldn't be able to see a huge difference between 98FPS and 100FPS what is going on here?

Sorry if this sounds obvious, but do you have the latest driver and tried re-installing it? Do you get the same problem in any other game now?

Also, try getting a copy of nHancer, and changing the settings in there to see if that improves things.
