I just installed the client, have the latest driver for my Nvidia Quadro FX 5600 (as of last week) but when I start the application, I get the message:

This graphics card does not meet the minimum requirements...

Prepare3D will now exit.

I'm assuming that my card is capable, but something else is making it appear that it is not adequate.

Any suggestions?

I'm running Windows XP 32 bit.

Thanks.

I know nVidia quote the card as being shader 4.0 but I think something else is at fault here. I had to remove my FX4500 which is shader 3.0 but also reporting the same problem.

I've been on another task and this is my first chance to return to this still existing problem. As previously noted, the Quadro FX 5600 card supports Shader 4.0 so that shouldn't be the problem. Is is possible that the client is misinterpreting this card as a GeForce 5600 instead of a Quadro FX 5600? Again, the error I get is that the card does not meet minimum requirements for shader support. A quick internet search makes it look like the GeForce 5600 only supports Shader 2.0 and therefore would not be adequate. I'm running standard display settings are far as screen resolution and color depth.

Thanks

Hi smguest,

The Quadro is engineered for CAD applications rather than real-time simulation. I had a Quadro on a mobile workstation myself and found it poor for simulation and FSX/ESP, but great for AutoCAD and 3D modelling. I don't know about the error message you are getting, but to be honest, I would probably not be using a Quadro with Prepar3D. I have read some technical reviews and they indicate that the GeForce and Quadro essentially use the same GPU, but there are some driver differences and minor hardware differences which could make compatibility issues become apparent. Can you try a newer GeForce to see if it makes a difference?

Could it just a case of the "Quadro FX 5600" entry in display.cfg, being missing ?

Hmmm - I don't seem to have a Prepar3D.cfg file but do have a Prepar3D.exe.cfg but it has no reference whatsoever to DISPLAY. I then did a search of every *.cfg file in the Prepar3d directory structure and there was no DISPLAY.Device reference in any of them.

In the display.cfg file, there are only a couple of NVIDIA Quadro references, Quadro FX 500, FX 600 and FX 700 (and a "Quadra" reference, the Quadra FX 2000) but none for the cards I have.

Thanks,

I looked into the code, and that error is a catch-all for cases where the DirectX device creation fails. The display.cfg is used to override user settings (like if the user set video memory to something higher than the card's capacity). It doesn't look like the display.cfg is related to your issue. I suspect that FSX and ESP would have the same issue. The old Quadro NVS 135M cards work in Prepar3D on XP. You might want to contact NVIDIA as this appears to be an issue with the XP-Dx9 drivers for Dx10 quadro cards.

Ah. The cfg file should get populated after your first successful run of Prepar3D. I don't think we have an Nvidia POC for driver support, but they should have support available through their website. A big part of the justification for the price of professional graphics cards is support. If that falls through, I would go to the driver archive and roll back to something older.
