I have just installed FS2004 which is excellent. But I have noted that the frame are less than 50% of those in FS2002 for some reason, ie 50 FPS in 2002 given the same set up translates to 17 FPS in 2004.Is that correct, this is even after setting the priority to highest in the task manager.I have FS Traffic 2002 installed, default Airports, default A/C.System: Win XPAMD FX 51 3200I GB RAMNvidia Geforce FX 5950Many thanks, Best Wishes to all,Chris EGBBUK

Generally, I found only a 10FPS loss between FS2002 to FS2004. It is mainly due to the clouds/weather system.Installing FS2004 will install DirectX9.0a, if DirectX9.0b isn't installed. Press Start, Run..., type dxdiag, OK. Let the DirectX Diagnostic stabilize, review the version installed. If it is not DirectX9.0b, download and install X9.0b from the Microsoft Windows Update site. Select the Display tab, ensure DirectDraw, Direct3D, and AGP Accelerations are enabled. If any or all are grayed out, reinstall the MOBO Controller Chip drivers (you may want to see if there are updated drivers anyway), i.e., Intel, VIA, SiS, AMD, ALi, NForce. Run the DirectDraw and Direct3D tests and not any errors.I would double check each setting between FS2002 and FS2004 to do the comparison. However, some settings are different or unavailable in each version. You might try an airport that is default in both cases to do the comparisons.W. Sieffert

Many thanks for your kind reply which was most helfpful, but luckily i still have directx 9.0b installed.Best Wishes,Chris

You should be getting better frames than that. I can get up to 20fps with default aircraft and scenery. I have aircraft on high, scenery on medium high, and weather on low with 8x AS and no AA. What drivers are you using on that card. I recoment 60.72 from guru3d.com.You must have a conflict somewhere. Perhaps ram speed is a problem. You should be running PC400 DDR with a system like that. Also check you BIOS to make sure your video card is running at 8X AGP.

Many thanks Wildo. I am presuming I check this when the ystem boots up.Best Wishes,ChrisEGBB UK
