Hey guys. I just upgraded from an Ati X800 pro to and X850 XT and my fps actually decreased. Anyone have any ideas as to why that would be. My power supply is 480W, 3.2E processor so you wouldn't think that would be a big deal but ya never know I guess.

Techies can't even answer this one?

Did you download the latest drivers?Did you keep the same screen resolution and color depth?Did the install change your AGP Settings?Confirm that FS2004 picked up the change in Options ->Settings -> Display -> HardwareConfirm that the frame rate lock is still where want it.IF nothing else helps, make a backup copy of your fs9.cfg (to fs9.cfx or something) And restart the machine. Sometimes this gets rid of an otherwise unexplainable problem. You will have to select your specic settings again. I do this about nce every six months as maintenance. If it doesn't help, restore you back up copy.Otherwise, you should have seen some increase, or at least the same performance, not worse. Most people's machines are CPU limited, not video card limited. I have an AMD 64 +4000 with 2 gigs of OCX EL DDR 400 RAM, ASUS MB, nvidia 6800 with 256 of DDR RAM and a Promise SATA RAID Controller with SATA Seagate Barracuda drives. This rig can display around 85 fps in an application as complicated and fast moving as Techland's Xpand Rally. (3D world very similar to FS's vector drawn, mesh and texture world.) In FS2004 with all of the FSGenesis detailed and buffer mesh loaded, FSGenesis landclass, FScene textures, Ultimate Terrain USA, NuRoads2, FS Environment, and Ultimate Traffic at 100%, I can get around 20 fps at a busy airport, 14fps at Dulles International with Simflyer's Dulles Scenery loaded. I turn off the traffic there and I can get around 28 with the same scenery. IF you check the resource useage, the CPU stays at 100% with fs9 running, it is a horse power hog. The addons load the processor even further. They are usually not hurting the video card if you have one of the more recent heavy end cards. (Xpand Rally has grass that moves in the wind, dust clouds, birds that look real in flight, deer that run across the road and environmental effects that are awesome. This game looked the same on an nvidia 5600 Ultra, and no real FPS gain when I moved up to the 6800+) I spent a fortune on the machine I built and I can get 50fps in the Virtual Cockpit of PMDG's 747-400, at altitude. With the PMDG 744, Approach is good, landing is around 18fps, and taxi around a busy airport is about 14fps with fat scenery, 2o to 22fps at default scenery (with 100% traffic and clouds).My point is that a video card upgrade may not add frames, but you shouldn't looses frames.Let's hope that FS2006(?) supports a more CPU load friendly rendering system.Dennis

I get excellent FPS with my ATI X800XT PCIe card with the following FS9.cfg display settings:[DISPLAY]UPPER_FRAMERATE_LIMIT=50TEXTURE_BANDWIDTH_MULT=60[TERRAIN]TERRAIN_ERROR_FACTOR=96.000000TERRAIN_MIN_DEM_AREA=10.000000TERRAIN_MAX_DEM_AREA=200.000000TERRAIN_MAX_VERTEX_LEVEL=20TERRAIN_TEXTURE_SIZE_EXP=8TERRAIN_AUTOGEN_DENSITY=4TERRAIN_USE_GRADIENT_MAP=1TERRAIN_EXTENDED_TEXTURES=1TERRAIN_DEFAULT_RADIUS=40.000000TERRAIN_EXTENDED_RADIUS=60.000000TERRAIN_EXTENDED_LEVELS=1242456Perhaps this will help your FPS.Jim
