I would just like to clarify that I'm perfectly content with the drop in fps that I'm seeing - I think it's entirely commensurate with the improvement in visual appearance. In my local area (near EGPE, so not terribly built-up) I usually get just over 30 fps with 3d clouds, trees etc and the Buccaneer; it drops to a still usable 20-something with the latest shader effects in action (there's a good bit of sea around here of course...) I consider that quite acceptable, given that my graphics card is not exactly powerful by current standards (Nvidia 7300GS) Although high performance on lesser hardware is nice, I think it's reasonable enough to demand powerful hardware for the nicest eye candy.

Are you still getting 20 fps? I don't see much difference between flying above the puffy clouds and flying underneath them... possibly slightly lower fps when flying higher, but I can imagine several reasons for that. Overall, I'd say the new effects seem to have the kind of performance penalty that I'd expected, and are well worth it... one can always turn them off if necessary, anyway. Did I also forget to mention how much more fun flying is with the more realistic turbulence that was added a while back? :-) Cheers, AJ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Switching to 2d clouds with these new shader effects puts me back up to running fast again. Also 3d clouds + drawing to multiple cameras/windows is another thing that seems to bring the frame rates down substantially. The last statement suggests to me that you're just maxing out your graphics card rather than something intrinsic to the 3d clouds vs. the new shaders. Do you see a change running the new shaders but no 3d clouds on single vs. multiple cameras/windows, in particular with high visibility? However, it's possible that the 3d clouds and trees are being loaded in a different way to the new shaders, in a way that is sub-optimal. I'm sure Tim will know :) So, we now have shaders for trees, clouds and terrain. Particles next? ;) -Stuart -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.

Shadows (aircraft shadows cast on to itself and onto the ground.) 2. Wet runways that reflect some sort of foggy, fuzzy something or other. Like glass effects except more wet runway-ish. 3. Proper landing lights that illuminate the scene. Curt. -- Curtis Olson: http://baron.flightgear.org/~curt/ -- Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
