Hi Rob,I'm afraid it doesn't work for me.

What are you using for Audio?Suggest you remove RAID completely (as in disable it from the BIOS).Did you follow my guidelines to the letter? It doesn't look like it -- you'll have to try drastic measures if you want to solve this problem.You're also at the outer limits of that SilverStone (PC Power and Cooling 800 or 1000 watt PSU might be better).4 hard drivesX2 processor2 DVD drives2 GPUshow many fans?How many watts is your system consuming? You aim for about 50% load at peak usage (i.e. 325 watts)Are you running coolbits to get the other display properties for nVidia?what are your results if you don't run SLI? are both PCI-E bus speed settings a 8X when running SLI?Are you able to turn OFF one processor via the BIOS?The location of the FS is not relevant (for this issue), the fact you have the RAID controller enabled is the issue.

More than likely the "Fix" above won't work. I have tried it and had 3 other people with like systems try it and it didn't work. If there isn't texture corruption with the 80's series drivers and the 7800 GTX you would be in the minority. Good luck Though.

The interesting thing is, if I power off and put the monitor in the other socket, it sometimes works for hours. If I then shut down and start up, it doesn't work. I can repeat this by changing back to the first socket and it may work.George

Here's the proof. I've just powered down, switched the monitor to the other socket and:Perfect! However I still can't run in full-screen mode.George

is nView enabled or disabled?I don't have the option of running two PCI-E at 16X -- have you tried running them both at 8X.

Sorry Rob, this is the latest version of the Asus A8N32-SLI Deluxe which doesn't have the "flip board" to set SLI. There is no way to set 8x, it is 16x on both slots by default.nView is in the system tray but I don't have a desktop set.GeorgeBTW, I've been running FS9 since my last post (20 mins) without a problem. 2000ft, 249kts at 60fps (locked at 60fps) and no blurring of the ground textures.

George,No, I don't have the Asus board (and yes it is an A8N-SLI deluxe) that requires the "flip board" (and I do know what you mean) -- all that is required is the connecting SLI card that goes on top of both Video cards that joins them (assume you have this connected?)There should be a utility that comes with your motherboard that permits you to set your bus speed 1,2,4,8,16 for each 16x PCI-E slot.But as I understand it, the A8N32-SLI should provide the same switching utility and you should be able to set the speed.Disable nView completely.No blurring of ground textures? have you tweaked FS9.cfg?

Yes I've tweaked the FS9.cfg for my other machine which is a 3.02GHz Xeon with 1Gb ram and an FX6800 Ultra with 2 18" TFT monitors..You may be interested in the reply I received from nVidia:Thank you for contacting NVIDIA Customer Care.We recomend that you download the driver version 78.01 from our website which is compatible with your video card.For further information, please visit the following link :http://www.nvidia.com/object/winxp_2k_78.01.htmlHwever, there is no mention of FX7800 GTX on the download page.George

Unless you can get a hold of an device driver engineer at nVidia support, I wouldn't waste your time going thru the "consumer" channels with nVidia.Anyway, you didn't answer regarding the bridge that goes across the top of the two video cards? You still need this bridge even on the A8N32-SLI. What ASUS did away with was the Single/Dual card that slotted in the bottom between the two PCI-E cards. I have a solid PCB connector in my A8N and you get the flexible one A8N32 -- but it still needs to be connected.If you're running FS9 in windowed mode then you definitely will not be running it in SLI (probably why you have more success)"all important SLI bridge connector which in this case is made of a soft flexible material"Also, did you say you have 2 monitors hooked up and enabled? Suggest you disable one monitor for now.The basic rule of thumb to make this work correclty is eliminate ALL variables:1. Stay with a "non-modified" FS9.cfg2. use one monitor3. BIOS settings suggested earlier4. nVidia display driver settings5. test with one card, then test with two if all is good with one6. make sure you have the Asus SLI switching software installed and set correctlyOnce you get it working reliably and consistantly, then start adding stuff back one at a time. It is a pain in the #### process but, 99% of the time this process will solve or at least identify the issue.But don't go to nVidia to solve the problem, they've already acknowledge they ain't gonna do anything more about FS9 (per the type of response you got and I got).

Why do you think you can diagnose my problem? A friend has the Asus A8N32-SLI Deluxe with a Pentium IV and 2x 256Mb 7800 GTX's and he doesn't have a problem. That is of no help to me.George

I don't think I can diagnose your problem, only you can do that. I was giving you suggestions.Don't change FS9.cfg because there are values in there that may or may not work with the various hardware installed and since your having problems this is not a good idea until you resolve the problems.Did you select 2D Performance mode for you profile? Regardless, you'll NOT get SLI in Windowed mode under FS2004.If you want to blame nVidia you can, but the bottom line is that doesn't help you get from A to B.Anyway, I'm done with the guessing at what George has or has not done game -- if you don't want to provide details then best of luck to ya -- I was just trying to provide assistance -- if not for your benefit, for others that might be reading this.The facts still remains that FS9.1 can and does work well under 81.95 drivers in SLI for many people using 7800GTX 512MB cards.Rob.

Hi George, I know you been sending me email on this subject which is a bummer. I don't know why this is only affects the GTX series. Also it will not let you install older drivers no matter what you do. I'm not trying to be direct here but if there was a fix for this don't ya think others would be trying this.It makes me sick that I have to send this card back when I was looking forward to using it. I also feel you shouldn't have to disable things on a computer or in the BIOS just to get this card to work. FS9 is a three year old program and ya already know how I feel about Nvidia fixing it...lol. I have my system set up in Raid 0 and have never had one problem with it. It is also very fast.To prove a point here I just installed the 6800GT card and downloaded the 80 series drivers. The texture is STILL fo-bar but not as bad.The 80 series drivers and the GTX are geared towards 3D performance. If you notice the clouds look great in FS9 using that card that is because they are in 3D. The ground texture is not. All the changing and disabling in your system will not solve this issue. This is a 100% driver related issue and until they come up with a patch or a updated driver and that is IF they do my suggestion would be to either send the cards back or exchange them. Either way you will not be able to use the 80 series drivers in FS9 , FS9.1 what ever. I am no geek here but I have spent countless hours on the card. Changing out motherboards, hard drives, memory,CPU.You can spend all the time your heart desires like the rest of us have but I have come to the conclusion that the 7800/512GTX will not work in FS9...Mike

Hi Mike,I have found a fix. When I get scrambled textures, I power down, switch the monitor to the other socket on the card and power up. FS9 then runs great with no texture scrambling or blurring and 100 fps over custom autogenned photographic scenery. If I then power down then up again, FS9 shows random ground textures. To fix it, I again power down, switch the monitor back to the original socket and it's fine again.I can live with this until a fix is found.George
