Nvidia 9500 GT running but not with all its power

[Zoker]

Hi, I have my 9500 shown up using kernel flag graphicenable=yes.

  Chipset Model:	GeForce 9500 GT
  Type:	GPU
  Bus:	PCIe
  Slot:	Slot-1
  PCIe Lane Width:	x16
  VRAM (Total):	1024 MB
  Vendor:	NVIDIA (0x10de)
  Device ID:	0x0640
  Revision ID:	0x00a1
  ROM Revision:	xx.xx.xx - internal
  Displays:
SyncMaster:
  Resolution:	1680 x 1050 @ 60 Hz
  Pixel Depth:	32-Bit Color (ARGB8888)
  Main Display:	Yes
  Mirror:	Off
  Online:	Yes
  Rotation:	Supported
Display Connector:
  Status:	No Display Connected

but its performance is not as smooth as in win7. Mkv videos at 1080p lags at fast motions, Modern Warfare2 shows bad texture, Aperture can't be install and stuck at entering serial numbers step (hang up after pressing continue). However, I can run Photoshop, Modo quite well, but a bit slower than in win 7. Is there anything I can do to get my graphic card running with its full power? Please help

I also got the feeling that my 9500gt doesn't run at full power, especially in games! In portal for example I had to lower the settings that were recommended for my system in order to get a good frame rate.

elouvee, have you do any DSDT? I haven't try it because I'm not so sure what it is. Do you think that could cause the problem we have?

Is it the DDR2 version? I own an XFX 9500GT 1GB DDR2, and I had the same problems with videos in Mac os.
