Have you reinstalled drivers?

Hello,I have a similar system:Intel P4 1,7 @ 1,9 OCASUS P4T512 MB RAMBUS 800 Mhz, overclocked with FSB ~900 MHZBefore: GeForce3 64MB (235:515 OC)After : GeForce FX 5600 256 MB (355:585 OC)Gainward FX PowerPack! Ultra/780 XP Professional Dual-DVI(great with my two LCD's!)Driver: 45.23[ Note: I can OC the FX to 401:602 max. but with a chance to have scenery errors in ~3 of 10 tests. 380:590 is rock stable with FS2004, but not with OpenGL games. OpenGL does not like overclocked Cards so my compromise is 355:585 at the moment without using Powerstrip ]When I benchmarked the Learjet sitting on a runway at KJFK with heavy 3D clouds, the fps rate was indeed the same ~12-14.Without any clouds the FX always goes to my fps limit of 25. Even in big sceneries like KJFK or Manhatten city.The total maximum FPS in high alt over the sea with "no weather" is ~80 fps with the FX.What really helps with clouds is the FSW cloud fix.To sum up, the FX reaches my fps limit without clouds. That was not possible with the GeForce3, esp. with denses sceneries.With 3D clouds, the FX has much more power than the GeForce 3 inflight. It depends on how dense the clouds are. The range goes from 6 to 18 fps.Also, the ground textures do load up without any delay. You see 256 MB working very nicly with the txture monster FS2004.The GeForce 3 really had problems to load ground textures quickly.So, my FX 5600 is not a 5900 Ultra and what I have expected was met: - FS2004 with my Add-ons is flyable with a 5600 and I even can reach my top fps sometimes. What helps, I live in a hot area with many sunny days :)
