While trying out the demo (as adviced to in earlier thread) I encountered these issues1) I see flickering objects and shimmering textures. Had similary problems in FSX but solved that by setting up a profile in Nvidia inspector for FSX according to a tweaking guide. In XPlane I see no entry for XPlane. How can this be solved?2) I added manually cloud layers and got rather descent performence. Then I downloaded real time weather that resulted in a less cloudy sky. Then I saw drastic drop in performence. Big drop in fps. Why? Rendering options unchanged.

First thing is to make sure you have your GPU drivers up to date.You can use you FSX nVidia Profile for XPX just add X-Plane to it, or create a new profile with the same settings.With Real Weather it's going to be different then what You create.Look at the blogs in my sig for more info.

There is a profile for x-plane in NVidia Inspector. As for the flickering objects, make sure your using the 32 bit color depth.

I don't find any x-plane profile neither do I see how I could add XP to the FSX profile. I use 32 bit color depth.

If you HAVE a profile for FSX you just need to ADD the XPX.exe to that profile.If you don't know how to do that read the manual it's very easy.

Yes that was easy. But solving the issues that way wasn't easy. If I enable AA in NVIDIA inspector for XP the whole display get corrupted. Setting AA inside XP seems to have no effect and I still think I have bad image quality with shimmering and flickering textures.

Is your GPU driver the latest?Do you have HDR on, if so turn it off, then try.Make sure your screen resolution is 32 bit not 16.What are your system specs?

Yes got the latest drivers. Checked at NVIDIA siteNo HDR off since I have discovered that turning it on results in huge performence loss.Resolution is 32 bit, checked againMy system specAMD Phenom II X4 965BE 3.4 GHz4 Gb PC6400 RAMNVIDIA GTS250 1 GbWin 7 x64Noticed that AA seems to have been enabled after restarting XP
