This option must be really new because I don't have it. I have two 3/1 options, a 2/2 option and a 1/3 option. Either way, I'm now using 2GB. > My understanding is that the performance hit from enabling high memory > support is actually fairly small; if you have more than 1G (where the > fix is unlikely to break anything) it's not worth worrying about. > My guesses is, as has already been suggested, that something is messed > up with your video driver.

For testing some other software I upgraded to 2.16.6.16 2 weeks ago (when I still had 1GB) which resulted in the same problem. I then went back to the previous-compiled 2.6.16.5 version which worked flawlessly. It is only now that I have actually rebuilt the 2.6.16.5 kernel (due to RAM upgrade) and am having the same problem. The NVidial kernel and glx (to be sure) were also rebuilt. I did a bit of testing last night before I went to bed and it seems that no matter what options I use in the kernel I'm getting bad performance now from the graphics card. It still gets > 4000 fps with glxgears though, so I'm not 100% sure it is the graphics card. The question I was meaning to ask is what the ideal kernel settings should be for 2GB of RAM... from there I'll look for other explanations why the 3d isn't performing well. Should I use 2/2 *and* highmem, or just 2/2 ? You suggest the highmem does very little, but it's there for a valid reason I take it. Thanks for the answers, Ralph -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.2.2 (GNU/Linux) iD8DBQFEljNWCt0ZF9kLPvYRArMnAJ49+k5iZbZGr+UBiPOMtYCDzpJ0QgCghWkt KHDb0KCFbAnyyAQGymJvd70= =Weyw -----END PGP SIGNATURE----- -- [email protected] mailing list
