Hey everyone. You might remember I did a speedrun of Jedi Knight. I think I want to redo it for several reasons, one of which is getting a better quality capture. I found that amazing 3D acceleration fix, which works (yay), but I seem to be at a constant 30FPS.

I've heard that some people are getting much better framerates with V-sync off, but I don't see an option to do so in game.

I've got an ATI Radeon 4870. Any tips?

JK Speedrun??

Yeah, current version is here:

Want to improve on the time as well.

Use fraps, JK doesn't have Vsync as far as I know.

I have never noticed a cap. On all my cards, which have been either 3dfx or nvidia, I sync to refresh rate and get 60 or 75 depending on my monitor. You can activate the advanced display mode by passing -displayconfig I think (it's in the FAQ on the main page).

(oops, not in FAQ I guess, it's in trails guide, though: http://www.jediknight.net/trail/guide.html)

Speed run?

man Trail's guide takes me back.

There's a reason that video only has 4 stars.

Make sure your video drivers are not set to force Direct3D VSync on. Both nVidia and ATI control panels have this option.

I don't have Vsync forced in my settings. In fact I still get 30 fps with Vsync explicitly set to always off in the ATI settings. This happens whether I have Fraps running or not.

(edit) Tried the framerate command. It's telling me that I'm running at 60 fps solid but I can definitely tell it's actually around 30. Playing in software mode is much smoother.

That run was definitely done by a noob.

If it's 60 solid are you sure the vsync isn't on? It should fluctuate if not...

I still have that speedrun on my computer, was interesting to watch.

good luck and let us know how it goes

Well maybe it's on somewhere. But I can't find out where. I didn't see any refresh rate related features in the Advanced Display Config section. And the problem still happened with "Vsync off no matter what" set in my ATI options.
