glxgears running smooth but only 240fps?!?

md_lasalle · 06-13-2007, 11:36 PM

Hey all

I've recently bought a mac book pro 15" as a work computer because ill be making sure the game we are developing runs flawlessly on Linux and Mac.

so, i have triple booted the system, with OS X 10.4.9 , windozeXP pro, and Ubuntu 6.10

i've struggled, but finally got my X1600 to be recognized properly by glxinfos

glxgears was laggy before i did the install, but now, it runs super smooth. I was curious, i started glxgears with the -printfps option, i saw an average of 240fps, which for me, is more than enough, since after 60fps, there not much difference anyway.

As i was reading on the Net, i saw people with radeon 9200 card hitting 4000fps and more

This brings 2 questions :

1 - Is my video card really properly installed ?
2 - Does my video card has some sort of built-in mechanism that prevents it from going uselessly further than 240fps to minimize the heat, because that laptop is getting really hot easily.

Thanks for any inputs

As much for my curiosity as yours, try "glxgears -info"

Depending on the distribution you are using, I think glxgears is fudged. Lots of gurus get very upset at the proclivity to use glxgears as a benchmark, and I'm sure there must be some good reason for that.

That'd be in a 150x100 pixel window. I can get 2500 FPS at that size, but when glxgears runs maximised it goes down to about 203 FPS.

I think anything above 200 'maximised' FPS in glxgears is pretty good.

What alternative is there?

glxgears has been present on every distro I've tried. I might be wrong (for reasons which are beyond my understanding), but I see no problem with using it as a method to determine the effectiveness of various tweaks on a specific machine. Or am I wrong?

I really don't know the answer. You are probably right about "effectiveness of various tweaks on a specific machine," but the OP started out by saying, "Somebody else's machine runs glxgears faster than mine."

Yeah, I guess that'd get old pretty quickly for a developer.

For me, running maximized or tiny window didn't affect the fps at all, always between 240~250

I guess the real test would be to install UT2k4 and see how that goes :P

md_lasalle · 06-14-2007, 10:34 PM

allright after tested ut2k4, highest resolution, with all maxed details, i was able to play without dropping below 60 fps... so i guess it is well installed
