ATI 79XX cards performance

Currently I'm running X-Plane 10 on an ATI HD 7950oc' card, but even with cars and clouds turned off I experience no better FPS than with my former GTX560 - 1GB card (same settings but with cars and clouds!). It's "flyable" but far away from what you would expect.

Laminar will be adressing ATI+windows' car and cloud performance in the next major update but it seems that there is much more to do for good performance on 79XX cards.

If I understood correctly this is a special 79XX "bug" and I'm still not sure whether to blame ATI, Laminar, both or myself for it. :Whistle:

Is anybody seeing "satisfying" FPS in XP10 on a HD 7950 or 7970 card or is it all the same?

That would be very sad because with 3GB VRAM and now "reasonable" prices latest ATI cards could be very interesting for X-Planers.

Thanks and good flying

Flo
