Comments on: X-Plane Hangs on Start with NVidia Cards

Hi.

I’m using a Nvidia GeForce 9800GT and when using a Matrox Triplehead2go, X-Plane hangs on start-up.

I’ve updated and downloaded every new driver possible (the triple screen looks amazing). But X-plane hangs.

When I revert back to single screen (original setup), X-plane loads.

Anyone got any ideas what I could try?

Thanks.

I just wanted to post it since I saw that no one else has. I didn’t expect better frame rates in X-Plane since forcing AFR for other games that didn’t have an SLI profile also resulted in lower frame rates. During the test, GPU usage is at a constant 24% and CPU usage is at 7%(almost 2 threads) so I wouldn’t expect SLI to be beneficial at this point anyway. I can however set Anti-Aliasing to 64x(overkill, I know) and Transparency Anti-Aliasing to 16x super-sampled with both GPUs at 43% usage and still get over 80FPS. I have found that turning on FSAA in X-Plane yields greatly lowered framerates compared to turning FSAA off in X-Plane and overriding anti-aliasing in the Nvidia Control Panel.

I’m really looking forward to all the improvements in X-Plane 10. Thank you for all your hard work!

Interesting…it makes sense that AFR rendering would have poor performance – X-Plane has (as far as the driver is concerned) inter-frame dependencies. (This is more because OpenGL doesn’t provide a simple clean way to break these dependencies that I am aware of than because of X-Plane’s design) so there’s a lot of data transfer going on between the two cards.

Also, we’re not usually fill-rate bound in X-Plane 9 on high quality DX11 cards, so the second card is probably not necessary.

I already posted above but wanted to show results with SLI. Just FYI.

HELLO GUYS, I HAVE TO BUY A NVIDIA GTX 460 with 768 MB of RAM MEDIAWORLD DDR5.
WITH FSX performance is excellent, OR DO NOT GO ON MEDIA AND MICROSOCATTI 60 FPS with peaks of 100, the SET WITH MEDIUM-HIGH.
HOWEVER, when I started X-Plane 9 HO WAS NOTED THAT THE SIMULATOR TO THE MAX 20 FPS, I HAVE TRIED TO WRITE THE KEY PREFERENCES, but nothing changes.
Then I did a test I removed the NVIDIA MIA, I HAVE REPLACED MY OLD-Vapor-X ATI 4870 DDR5 2GB of RAM.
I DID THAT I WAS RESULTING FSX microswitch, WITH A MAX FPS arriving at 40.
When booting X-PLANE WAS Smoothly 9.
Now there I ask this question, is it true that X-PLANE is optimized for FSX FOR NVIDIA AND ATI?

HOW peformance is more powerful than the GTX 460 CHE THE VAPOR-X 4870.

OOOPS – delete my stats here. I was dreaming that I had a GTX485 … really it’s a GTX285! Must get a new card next week … or a whole new PC . Or a Mac Pro …

Plugin problem? If you remove third party plugins does that stuff go away? (If it does you’ll need to contact the plugin author.
