For the record, I'm running OS X 10.3.5
Using the default settings (640x480, 16 bit, medium sound quality, using OpenGL) with the remix sound packs, I get frames/sec: 242/131(msec)=184.732824

There is a line in the uqm.out saying OpenGL renderer: ATI Radeon 7500 OpenGL Engine version: 1.3 ATI-1.3.28
This kind of looks to me like it is using the right renderer..  

Anyway, thanks for the help.

Hi

I recently started playing uqm again after a bit of a break, but was disappointed to notice that it runs really slow and jerky.  I've got an iBook (900 MHz, 384 megs of ram, ATI Radeon 7500 mobility graphics card) and it should run better than that - in fact I remembered that I'd had it playing smoothly before.

I tried updating from 0.3 to the 0.32 CVS build, but no luck.  I tried removing the remix sound addons, and even the standard sounds but no luck.  It only ran slightly smoothly if I quit every other open program and launched in fullscreen at 320x240.

I then tried unchecking the "use OpenGL" box, and it works much better.  At 640x480, with high quality sound, it's perfectly smooth.  

Can anyone tell me why using OpenGL is actually slower?  And what difference does it make in terms of the game?  Thanks.

I've downloaded the uqm music remixes, and put them in a folder called "uqmremix" in the addons folder in the package, but there isn't any new music.

The instructions say to add "--addon uqmremix", but how do I do this if I'm using the mac application?
Thanks.
