I am using a BFG GTX260 nvidia graphics card and after downloading and installing the latest drivers, a program name PhsyX was also installed. As I understand, FSX is not affected with this feature. With that being the case, is is OK to go ahead and uninstall this portion of the nvidia driver package?ThanksWilbert ASUS P5Q SE PLUS/Thermaltake W0106 700W PSUIntel QX6700 Quadcore - 2.66 OC TO 3.2Vista Ultimate 64/CORSAIR XMS2 DHX 4GB (2 x 2GB)2x150GB SATA WD Raptor- No Raid/2x320GB SATA WD SE16- No Raid2x IDE Light-On DVDRW 165H65/BFG GTX2603x SILENX 120X25MM FANS + 2x 10in XCLIO Wind Tunnel Case FansDanger Den Water Cooling/Enermax temp/fan controllerFSX ACC@ 1600/1200 |UTX/ASX/FEX/MTX/ASA/REX

Hi,Not sure of the consequences of uninstalling, but if you go into the Nvidia control panel, PhysEx can be disabled with a click of the mouse. That is what I do rather than uninstall, and have had no issues.RegardsBob G

If you don't know what this is, Nvidia purchased a company called Ageia a while back - they were trying to market addon cards that did dedicated physics calculations and "PhysX" is what their API is called. Nvidia took the tech and made it so that their GPUs can execute the code for it in games that support it. There aren't really that many games that do though, and obviously FS is not one of them. I don't think you need to disable it, it can't even do anything in FS.
