Any possibility of applying a 30 fps cap in Batman Arkham City?

Joseph DeGarmo · Jun 10, 2015

The stutter in this game is ridiculous. I tried running in DX9 mode, turning off in-game AA, and forcing a higher resolution with DSR. Even with PhysX off, I still get some stuttering when flying. My PC is way over the game's recommended specs and this is stupid. So I figured that as with a few other games, I would bite the dust and cap the game at 30 fps to remove stuttering while maxing out all graphics settings, including running the game in 4K DSR mode. But when I apply the fps cap in RivaTuner which runs from EVGA Precision X 4.21, the game refuses to load the stages. I even tried editing the framerate values in bmengine.ini, but that did not work. Is there any other way to apply the 30 fps cap in this game? Like NVIDIA Inspector or something? I expect to have to do the same thing in Batman Arkham Origins and Arkham Knight, so the fix would apply to those games as well.

Put in a low performing GPU. Then it should run under 30fps.

CPU temps?

Joseph DeGarmo · Jun 10, 2015

CPU temps are fine. I don't want to run the game at under 30 fps. I just want to lock the game at 30 fps while running it on maxed settings in 4K resolution.

So you are not worried about the stuttering? Just getting the game under 30fps?

I think you should reserach fixes for the stuttering instead eg http://steamcommunity.com/app/200260/discussions/0/864978109442542023/

No, stuttering is bad when fps is between 30 and 60 fps. I just want to know if I could just run the game at 30 fps at all times. Do I have to try to use NVIDIA Inspector?

What display are you using? Please tell me it is NOT a TV.

Ninjawithagun :

1080p 60 Hz PC monitor (no G-sync)

You can "software-sync" via MSI Afterburner + RivaTuner statistics server.
Mainly, it's the latter utility doing the job, but the former is nice to have around anyway, and I'm not sure it would work without it.

From RTSS, there's an option to limit the maximum FPS under a certain value. Set it to 30, disable V-Sync in-game and you're done.
Used it myself to circumvent the 30-fps lock Dead Space 2 has when running with V-Sync active.

Of course, for this to work, you need to have the software running in the background before launching the game.

But doing that causes the levels to not load. Well, anyway, I put the game on DX9 mode, set the AA to FXAA high, and changed the resolution back to 1080p. Stuttering has decreased a lot under those settings. Though performance is not perfect, this will have to make do. At least it does run at 60 fps about 95% of the time with PhysX off. I'll need to use SLI or a dedicated PhysX card for this game. So I'll just leave it at that.

Heh...sorry. I completely missed the part about you saying you used RTSS...silly small mobile I'm reading this stuff on

PhysX pretty much require a dedicated card for them in any game right now, even with old games and even with single Nvidia cards to begin with, so if you've got that enabled, it's most likely the cause of stuttering.

Other than that, don't know what else to say but "I'm sorry for you". Feels weird that capping the FPS to 30 makes the game crash tho...I'd expect odd mouse behaviour or the usual stuff, but a complete crash strikes me as odd...
