After reading about FPS, I remembered that I was going to share one nice tremulous configuration command.

So, if you have an LCD and your FPS is higher than 60Hz, you must enter this command:
/r_swapInterval 1

Your FPS will be locked to the LCD refresh rate (usually 60Hz, sometimes higher). This removes the screen-bleeding that happens in tremulous very often on LCD screens, and generally improves smoothness of the graphics.

Also, you should always enable "Vertical Refresh Sync" (vsync, vertical sync) in other games to achieve same effect.

Just try it, and compare.

I tried it, and I'm disappointed... I haven't seen any graphic improvements, but I'm like in a big lag... When I set back to 0, it was ok.

btw I have: AMD Athlon 4000+ dual core 64bit, ATI Sapphire HD 2600 XT, 2GB RAM.

So I don't think I have such a wooden PC.

Was your FPS locked on ~60 after using this command?
If no - somehow it was not activated.
If yes - then I have no idea, maybe some VGA drivers make vsync work weird...

Generally speaking, vsync removes screen-bleeding that happens on all LCD displays. You can see what is screen-bleeding if you look at some highlighted textured wall, and start moving your camera up and down. You will notice visible lines where textures were not redrawn.
If you dont see anything like what described - then obviously you dont need enabling vsync

That screen bleeding happens on CRT too. With vsync is better view, but lower FPS and lower reactions becaus it always waiting on whole rendered screen.

I played often with vsync, because it was better and that distorted screen with vsync off was ugly. But new games eating too much my fps and with vsync off it was more playable, more smooth (more ugly) so I using vsync off :-/

Well, I hope your computer does not think tremulous is 'new game'

I have old computer. I started using vsync off before I found tremulous
