Isn't the old card (ATI 9800XT 256meg) better than the new one (Gainward 7800GS 256 megs)?

Hi Karstenyou should try to maximize the AGP APERTURE SIZE in you PC BIOS.Normally it is set to 64M but FSX needs 256M.It worked for me!!! Now i can play at 25fps.Athlon XP64 3400+ - Geforce 6600GT 128M AGP - 1G DDR400 RAMByeFelix

I think this happens if you use the RivaTuner / ATI Tray Tools method of disabling shaders. It doesn't happen if you use the display.cfg tweak mentioned in the thread I pointed to - this method doesn't knock the shaders out completely, it just adjusts them to a more suitable load. That thread was started specifically to show a way around the twin wing problem. The start of the thread I linked to set out the original problem and if you read the whole article, 'cbuchner1' tells you how to avoid all those problems. I quote:" Leave UseShaders at 1, otherwise you would lose Vertex shaders that will be used for wing flexing and other animations. Now that we limit ourselves to shader model 1.3 or 1.4, you should set your water detail to "High 1.x" to get at least some water effects with shaders.You should have working runway signs, working wing flex, a generally an improved simulator performance now. It made the thing actually playable on my 7800 GS AGP model."I have very nice wing flex effects with this tweak.

I love this industry $$$. Once again software drives the hardware. A $45.00 piece of software driving people (me included, I spent $45.00 :-lol ), to spend hundreds if not thousands of $$$ on new hardware... What a great concept... and it works well... :7Give it 1 to 2 years for the hardware to catch up, then invest more $$$ on hardware to run FSX "properly".

What was your old card?

Rhett,Thanks - that's good advice. I think I'll just postpone any upgrades until next year when we know where we are at with vista, dx10 and dual cores. For now I can get a good 15fps flying light aircraft in the countryside. I'll spend my money instead on some vfr scenary which will improve things no end, and will not age quite as quickly as any hardware I might buy.

I have a 7800GT vid card and an AMD 3500 processor. Applying the tweaks on the forums gives me a very smooth 25 fps at most locations.Ray Keattch

Instead of building my own computer and tweeking up a storm to make a piece of software run, I'm really beginning to think the kids and I can learn as much or more about flight dynamics and aviation in that hobby - and probebly save some money to boot.Regards, KendallDell 8400 3.2 GHZ H.T.800 FSB/2MB L22 GB 533 DDR2X800XT 256MB/Catalyst driver - 6.9's6x Adaptive AA/16x HQ A/FIntegrated SoundDual Monitor: Dell 2405/1905CH Yoke/Pedals

Sorry but i have to say the fsx runs at 25fps on my machine posts crack me up.If it does then you must have all the sliders at the left and looking at something worse than fs9, not what you paid for.Otherwise you're just making it up so go away.

I have all the sliders to the right except-I keep autogen off (which allows the new high res textures to show-you won't see them with autogen on), water on lowest, and ai traffic 20-25%. No tweaks except bumpng up the fiber rate to .44 for almost no blurring. With this I get 25-35 as normal in most areas except high detail airports. Give it a try...you also need to bump antilasing, anisotropic, and quality settings on your video card all the way up-and likewise same settings in fs.Here is how it looks ths way:http://forums.avsim.net/dcboard.php?az=sho...id=246077&page=3.2 pIv, 3 gigs ram, 512k video card.http://mywebpages.comcast.net/geofa/pages/rxp-pilot.jpg

It is quite playable with my Athlon XP 3200+ ATI 9800 Pro 128 MB. Using some of the tweaks posted in forum. I haven't changed the texture size, just changes in the CFG and sliders.I would think a 3 Gig P4 is equivalent to my 3200.Bruce

>> Carsten,>> By machine specs I meant Graphics Card, Processor, RAM.>> Also after looking at your FSX Config file I can tell you>that > lowering the following settings will definitely give you>better> frame rates:>> You have the following set at high settings (at least they>are> high for my machine)>> Water-lower> AI Traffic-lower> Autogen-lower or none> Other traffic-lower or 0Interesting this one - 'Autogen lower or none'.I have always used autogen, but since I tweaked FSX, I don't use it anymore. The textures are good enough to give the feeling of ground features - especially with the demo of the new Horizon VFR scenery.FPS and smoothness are great with autogen off, so I have been able to put the traffic sliders way up. In fact, for the first time I actually feel autogen spoils the relism for me - the cartoonish look of autogen spoil the pin sharp textures.AMD 35007800GT card1Gb Ram.This is enough for quite smooth performance.Ray Keattch

Felix,I would like to know more about this and how to do it. Do I need any tools to do it? I was wondering if this could be one of the reasons why people with the same equipment can get different FSX performance.thanks Daryllyou said;"Hi Karstenyou should try to maximize the AGP APERTURE SIZE in you PC BIOS.Normally it is set to 64M but FSX needs 256M.It worked for me!!!

It worked for me too.THANK YOU FOR SHARING THIS TIP!!!I simply have doubled my FPS like that, BAM!, changing the BIOS setting from 128MB to 256Mb.I was about to revert to FS9, since FSX was unplayable on my four years old rig, but now I'm getting acceptable FPS - 15FPS with low to medium low settings.My specs (don't laugh):Dell Dimension 8250, 1GB RAMBUS, 2.6GHz, ATI RADEON 9500PRO 128MBI'll add another 1GB over the weekend (I need it for rendering stuff anyway).--M
