Hello,

 

I would like to change my current GC an old GTX570.

From your experience, which card performs better in X-Plane X, NVidia or ATI, in Windows 7 ?

I've read I need a card with a lot of RAM, at least 4Gb.

NVidia GTX 770.

With ATI you can consider yourself lucky if you have a driver version that has a fully functional OpenGL support.

The more, the better - for obvious reasons :rolleyes:. But you don't necessarily need at least 4 GB ... I still had quite reasonable results with my 2 years old GTX 580 (1.5 GB) as you can see in my videos . Since 2 months I also own the GTX 770 (4 GB), and I could turn the rendering options even more up (especially the texture resolution).

I would go nVidia. I've had ATI before but they've given me much trouble (especially when flight simming). First I had the 5870, then the 7970 and now I have the GTX780 and, to be honest, I'm quite done with ATI. 

Does the model make a big difference with same VRAM? I'm also looking at upgrading to a 4GB card in the next few months; will a GTX770 4GB give noticeably better performance than a GTX760 4GB?

Here is a video to give you some idea of the frame rate differences using some of the latest most graphics intensive games.......

 

And what about the latest new AMD R9 290X ? According to the tests, they are performing like a GTX780 on many games and are better than the GTX770.

Seems rather like a 680 to me:

This is a speed comparison, but keep in mind that prices have changed since this review, and 770's can be found for much cheaper now. (And 780s have dropped as well)

 

Also be aware that ATI open GL driver support has not earned the greatest marks in the past. (not sure what its like right now)

 

FSX users also tend to go Nvidia, which may or may not be helpful information for you.

Are you joking? At the moment all newer AMD Driver are no longer able to handle HDR correctly in X-Plane! It looks like their driver support is steadily declining.

Not when you can find a 770 for a lower price, since it is the 680 on steroids (higher clock rate for the VRAM and better cooling)

I understood there was a problem with a specific driver (13.11) that could be resolved by using an earlier version. (13.9)

 

As I said, traditionally ATI open GL support has been perceived to be spotty, but that's not always the case.

 

Even so, last I knew it was acknowledged that the problem might be coming from the X-plane side........

Interesting, cheers. Seems like the Titan and the normal 780 are very similar. The 770 did seem to have about 10 frames on the 760 in most situations but will that also apply to XPlane? Some of the comments for this vid suggest an overclocked 760 is probably the best cost performer.

Not quite. This is guesswork by Ben, since AMD so regularly screws up. But that even the newest stable release 13.12 fails, indicates that AMD simply doesn't care.

Be careful. The main performance boost for X-Plane is the amount of VRAM. You can get better results from a 770 with 4 GB than from a 780 with 3 GB. At the moment X-Plane doesn't use so many shaders, so even smaller cards can achieve the same performance if they have as much VRAM available, but this might change in the future since X-Plane wants to make better use of the shaders.

That's what I was wondering. So in X-Plane a 4GB 770 won't make much of an improvement over a 4GB 760?

Thanks for the informations. I will have a look what is available in french online stores.
