:hello:
Wow ! Le vieux topic ! :ane:
Jsuis retombé dessus sur google en cherchant un bench pour ma GeForce2 Ultra sous glxgears afin de savoir si ca passerait sous Xgl … :MDR
Jme rappelais même plus que j’avais déjà posté ça ! :ane:
Bon, sur mon IBM Thinkpad T42p :
P-M 1.7, 1 Go RAM, FireGL T2 128, 1600x1200@24.
Debian Testing, Kernel 2.6.15.4 fait maison, Xorg 6.9.

Conclusion sur le Powerplay (Radeon Mobility) :
- 50% de perte de performance avec l’underclocking du Powerplay !
- Perte très faible (~100 fps) avec le CPU au raz des paquerettes - Donc merci les drivers proprio !
Et voilou !
