What causes the Biggest FPS Drop?

**kenney001** · August 28th, 2007 05:58 PM

Headlong is basically ready for a Beta 2, except for one thing. The FPS on the level is quite low. On CMT snow Grove, I was averaging 100-150FPS, and on Headlong Im getting 90-120FPS, with Vsync on on a Radeon X1950pro. I am not real happy with these numbers, so what can I do?

-Shader details are on high with alpha maps controlling a cubemap (on 70% of them)
-I have alot of vehicles. 2 warthogs, 2 ghosts, a banshee, a scorpion, a wraith, and about 10 crates)
-I have a pretty decent amount of scenery. Including vehicle barriers, the light fixtures, the billboards, the palm-trees, the red triangle cones, the larger crates, etc....
-I have portalled it well, this is not an issue...

I am looking toward CMT and ZTeam, because of the quality of your maps. What can I do that would be most effective at increasing the FPS?

portalling and LOD's

ok....LODs? could someone give me an example of what numbers whould go in the pixel cutoffs? Also, do i need to export the superhigh, high, medium, low, for those to work? Or can i only use the one i have.....

lods are exported as such:
*permutation name* superhigh
*permutation name* high
*permutation name* medium
*permutation name* low
*permutation name* superlow

setting the lod cutoffs i usually set my values like:
200
150
100
50
0

sometimes you'll need to fool with the values to get a smoother transition between lod's.

Jeeze, my FPS is always around 30. That bad?

30 is the native framerate.

Yea mine used to be like that until I changed the FPS settings in the video option (I seriously never knew about it haha...). Now the game runs as smooth as butter now a days.

Lol, if you have seen a single CMT tag, you wouldn't be saying the things are quality.
But anyway, 90-120 FPS is actually about what my real Headlong on H2 runs on.
I know you probably don't want to do this, but you could make the crates a scenery item, meaning the game has to do less calculations for the physics and whatnot, but I'm not sure if you want to sacrifice the H2 feel for better FPS.
Try making LODs, and if that doesn't help, it looks like you'll have to take it from there.

On that FPS rate, you could make it feel like H2V...
