Low FPS only in one way

[lauren]

Hello,

I have a terrain from 37.000 polygons. There are only 3-6 pieces of 512x512 texture in it.

I use a Mac, but tested this stuff on 3 different Macs. The result is the same.

The problem:
There are about 4-5 point, space on the terrain where if I fly with the player the FPS will be extremly low: 4-7, but if i turn the other direction the FPS will be 60.
These spaces and these directions never change. So this is not a random event.

But if I restart the Mac, then i start the game again. Everything will be fine in every direction.
Then after a few game start and testing, the FPS problem come back again.

What would be this? Some memory problem?
Did I give enough information for you answer?

Thanks, Best regards

I create an image about my problem.



And the 2 main things that I noticed:

1. Mainly after the computer restart the problem is not exists for a while

2. The FPS is low only in that case if the player moves. If it stands, FPS is okay, camera speed is fine too.

We'd probably need the whole application, with sources and objects. Or you start to profile your app and see why it slows down. Which driver, btw?

what do you mean "driver" ? open gl or directx ? It use openGL.
