New Vegas Low FPS

post #1 of 16
Thread Starter 
Shouldn't my setup be able to run FONV just fine at max? I'm seeing pretty significant lag issues in many various areas, outside, inside, etc.

Is my Phenom II lagging it? I can't imagine the 6950 2GB would be the problem...

Make sure you have disabled vsync. You'll have to disable it in the configuration files* or in the Catalyst control center as the game defaults to vsync on even if you have it disabled in the Fallout New Vegas launcher.

*
1) Open up Fallout_default.ini which is located in the Fallout New Vegas directory (ex: \Program Files (x86)\Steam\steamapps\common\fallout new vegas)

2) Find iPresentInterval and set it to 0.

but then he would still have 120FPS topped off cuz he has an LED monitor, so thats smooth enough, in fact 60FPS is enough

Vsync is disabled, and that smoothed it out a bit. I've decreased the view distance to 3/4 of max and disabled both HDR and Bloom and that's helped some as well. Still glaring issues, though. When running next to an NPC, they seem to stutter and jump around a lot.

Might the patches help out? Perhaps I'll make sure the GPU is running 3D clocks and the game is using all cores when I get home (at work now).

I don't see why your comp shouldn't run it perfectly smooth.

Not all LED monitors run at 120hz.
