wow - impossible settings on my Mac Pro with the 5870 (1GB VRAM). Especially that you have clouds that high, shadow medium and HDR on, seem unreal to me at the moment ;)HDR outside view and cockpit is like 10fps less in the cockpit. Otherwise I could come closer to those settings.

No Goran, thats not exactly correct. There is still a lot (and really a lot), of the scenery that is processed in RAM and with the CPU (lots of the object geometry is "materialized" first there, before its pushed to the 3D card for rendering etc). Or all the scenery loading / processing, and not to forget AI, or the weather ...But its correct, that with XP10 there is now much more the 3D card can do (which gives a better balance than what we had in XP9 :) )

Thanks for correcting me, Andras. That's why I added the "IIRC". My bad.

Well, OK, I think I need to add some more.Of course, even though I have those cloud settings ... I have no clouds in that KSEA shot at all. But I just check that while I am writing this.And, of course, some outside views can be much better ... if compared to a plane with highly detailed cockpit (which can cost some more FPS). I have to admit, that I often tend to use the "not so complex" F22 (because for scenery test its easy to fly, and fast enough to cover longer distances).OK, here are my results with same. I just threw in a layer of "cumulus scattered" between 15800-178000 ... FPS dropped to 10-11 ... Well, this is where I would say, we are almost down, where it isn't that much fun to fly anymore :) (but please mind, all this, while having the above rendering setting! Which is quite a lot!).(oh, and I fly this at 1920x944 :) ... yes, its a bit odd .. because I fly it windowed on Linux).

2560x1440, same clouds but only 20%, resolution 2560x1440 (no win going down from that), and the settings that I'd like to keep - but there have to come some optimization in order to do so. FPS around 20 in this view, less in cockpit on the airport.

I'm having a heck of a time getting X-Plane stable. Seems like I'll get settings that seem to work pretty good, then suddenly my framerates will a take a dive for no obvious reason. Or I'll restart the simulator after the 10-minute time-out and my framerates will be 10 frames per second lower than they just were moments before. It's rather frustrating, actually.

Are you running any of the "special effects"? I found turning any of them on turned my system into a slideshow and massive dives...

here's a lucky guy with smooth FPS (not my video)

HDR is the killer for me. I can leave the other ones on, but disabling HDR does smooth things out. Shadows also seem to do a number on my system.And here was me thinking I had pretty decent hardware.

I did find some settings that work fine but I use nvidia inspector's profile to override all the AA and AF settings.I did notice a serious issue though. When I use this profile and disable HDR I get lots of odd colored textures, probably video artifacts. It's odd I was under the impression HDR adds to video textures not decreases hmmmAlso, how do you display FPS?

Data input/output settings screen. forth row of all available options gives you on-screen display.

That was awesome!HDR kills my setup too, and I have a beefy rig. I got SLI AA to work without HDR and it's amazing for solving performance problems, but couldn't force it with HDR checked. I'll keep trying.

Thanks got it. And then here's my issue (without nvidia profile) but with in game AF set to 16x and AA set to 8x, NO HDR.Psychedelic no?

Yeah,I had fluorescent green mountains yesterday.

Ok, so it's not only me... What system are you running? My specs are in my sig. The GTX570 is quite powerful. But the only way to rid myself of those blue and green colors is to run an nvidia profile.Which is too bad because without HDR and with 8x AA and 16x AF in XP10 the rendering looks nice and crisp. With nvidia profile I get a bit of fuzziness and "shimmering" (usually AA related) but at least I can fly it. I'm confused because I use the same nvidia profile in FSX and it looks amazing, everything is sharp and crisp. Must be the OpenGL difference or something.

Ryan,I added my system specs to my sig. I am not presently using an nvidia profile with XPX, but will definitely look at making an attempt at one. As is, I can't use HDR unless I want XPX to come to a crawl. It's funny though, I start out on the runway in the mid 20s, and progressively lose FPS after takeoff.Oh well, back to testing...
