The engine is still strictly single threaded, all that option for osx does, is to tell the graphics driver it should create a second thread for all the OpenGL stuff. On any other system, that happens automagically and doesn't any extra effort from the developer.

Does 2.3 support mutithreading outside of MacOSX or has this feature been included in the past.
If so, what is the command to enable/disable it.
I want to test something out and see how much mutithreading evens out the driver issues and GPU overload.

Thanks.

DP isn't multithreaded. All it does on MacOS X is to signal that the OpenGL driver shall run multi-threaded.

On other operating systems the 3D drivers do this by default anyway. If Apple did this right they'd just enable that behaviour by default - no idea why they want the apps to trigger it.

edit: My, I'm slow.

Lol, slow indeed
Thanks for the response guys.
Either way, my FPS doubled again when switching to 2.3
I installed 2.2.3 a few days ago (yeah I'm slow as well) and FPS close to doubeled there. Now it increased again by almost 80% !
This is too much greatness for me in such a short time. Great job guys.
I'm getting excited about the official 2.3

Noob question: Would compiling for smp yield a significant performance increase on multi-core and multiprocessor systems or does this require changes in the code?

You can't simply compile a program for smp. Optimizing it for smp environments needs severe code changes and as stated in other threads that wouldn't make much sense for Nexuiz, since any modern multi-core CPU should be fast enough, so that Nexuiz is not CPU bound.

yeah, I mean nexuiz does not really use that much CPU unless you're using mesa drivers, which is not even a part of the engine. If anything it would make sense to multithread the server, but even that wouldn't really be necessary because of what kadaverjack said, the multi-core cpu should already be fast enough.

It's like, you'd have to rebuild your whole house to change its heating installation from gas to heater mats.

Now imagine this with a LOT of C code
