Title: Frame drops while in external view
Post by: LocalToast on February 15, 2014, 03:38:36 am

Hey Forum!

I have been playing FreeSpace for some time now, but there is an issue I wasn't able to resolve:

While in external view (i.e. the '.' button on the keypad), my Framerate drops from a stable 100 - 120 FPS to under 30 FPS.
This is especially apparent in the "Blue Planet" community campain, in which I sometimes get 20 sec freezeframes combined with 1 - 5 FPS.
Is there any way to solve this problem?

Thanks in advance
- Toast

You're probably hitting issues with the Blue Planet deferred lighting code. Install the BP compatibility package (linked in the BP subforum), then try running with a recent nightly build.

If that doesn't fix it (and honestly I'm not sure why external view in particular would cause that...) we'll need to investigate further. Does this only happen when using a BP build?

Thanks, that solved the problem! It was really obnoxious watching the cutscenes with 1 frame every few seconds.

I'm still puzzled why this error only appears in the free external camera (Keypad '.') and not in 1st person or 3rd person fixed (Keypad '*').

It's a mystery! Some of the performance oddities with the deferred lighting code are just baffling, hence why those features still aren't in trunk.
