Possible Performance Gain

[MoroseTroll]

Ok... One more question: is there any possibility that TDM will be more multithreaded when Doom 3 will be opened?

Everything is possible, but it's more work than you can imagine. Many closed source parts are not designed for multi-threading (for instance the CollisionModelManager is using static variables), as I've learned the hard way when trying to parallelize the AI code. One needs to do at least a partial redesign of those frameworks.

Not sure if this is still relevant but:

glReadPixels ???

 

(edit: It's still listed in the FAQ as a problem... )

I think the issue is about eliminating pipes from lightgem shot receiving. And using glReadPixels directly from SDK was intended as a possible solution.

 

 

Right now the state is the following: Firewall issues would be fixed in 1.05 by eliminating pipes (hook WriteFile instead). This relevant code is already implemented and is working right now (in branch), but it is considered risky to ship it in 1.04. And everyone is busy testing a lot of other things

 

EDIT: by the way using glReadPixels directly wouldn't make performance much better I think.
