I seem to be experiencing noticable drops in my frame rate recently while playing. This has only happened after I had to reinstall cs after cs:cz borked my original installation. It used to sit quite happily at around the 72 mark with very little deviation from this. now during games I have seen it drop down to as low as 25. I have checked all my rate settings and have no extra textures running. I have installed the csru final edition but i was running this before the install with no problems.
CSRU FE installs an added cvar called r_detailtextures (or similar).
If it's set to 1 it can affect fps. Try setting it to 0.
Ended up having to totally uninstall csru and that seems to have cured it. Its odd because before I installed CZ it worked just fine with the csru pack installed. It was only after cz borked my steam installation and i had to reinstall that i had the fps problems.
I couldn't use CSRU for the same reason...uninstalled it and it worked fine.
(that was with detailtextures off)
Its a shame really because its a really nice package.
This is where my NS knowledge comes in, as detailtextures were most widely tested by the NS mapping community,
r_detailtextures has a very minimal effect on fps - it's utterly negligible unless you're running a terribly old video card, and then it's unlikely that the card would support detailtextures.
Also, r_detailtextures will only affect fps if it is both active AND there's a detailtextures set being used on the map (it requires a text file telling the engine what detail textures to render over what map textures - if it's not present then no detailtextures will be rendered). It's not what was causing the problem.

I've had weird fps issues too recently though, thanks to smoke grenades. It was all running perfectly smoothly til I switched to 32bpp, and now I'm back down to 16bpp I'm still dropping from 70+ to around 30 when I'm near a smoke gren. Most annoying.

GFK - what was nicest about the package? You could always just grab Half Life Model Viewer ( http://www.swissquake.ch/chumbalum-soft (http://www.swissquake.ch/chumbalum-soft) ) and Sprite View ( http://www.valve-erc.com/files/resources/sprview.zip (http://www.valve-erc.com/files/resources/sprview.zip) ) and you can pick through the pack for the bits you want, and skip anything that's potentially framerate-harming.
