performance drop with running xosview
Hello all, Has someone get a significant performance drop in an open-gl application with X 4.0.1-1.deb's ? Description: up-to-date woody (04.11.00) Kernel: 2.2.18pre11 (hey ALSA works now with this kernel; agpgart is enabled; this is a big NO Dieter Nuetzel said in the newsgroup 3dfx.linux.glide; but this kernel need it at least) Vodoo 4500 AGP Epox Motherboard with VIA KX133;256MB RAM; 600 MHz slot A Athlon If i play the game parsec (www.parsec.org), i get a good playable framerate without a running xosview; 85 fps max ([EMAIL PROTECTED]).(per key i from the game) The framerate drops to about 60 fps with a running xosview. This is not to bad; but if i move around in the game i get a subjective (info shows 60 fps) framerate of 1 fps (yes one per second; difficult to explain) Game tuxracer drops also, but not visible (framerate about 22 fps max) Anyone has seen this? Any hints? Kernel or X related or xosview bug or maybe parsec-bug? Greetings Reiner Stallknecht PS: Kernel 2.4.0test10pre? shows this also
