I've been out of simming for a couple years and I just installed P3D v4, I'm having problems whenever I try to go between fullscreen and windowed mode where the eyepoint seems to get messed up and the zoom changes making everything blurry. It's hard to explain, in VC I end up looking upwards to the left at the headliner and when I mouse-look it seems like I'm using a fish-eye lens or something. Reloading the user aircraft fixes it but that's not something I really want to do at FL330 every time I try to look at a chart or something in another window. I'm running Win7 still @ 1920x1080 and most likely a very outdated driver for my GTX770, I'm working on that. I did some searching, read some threads not really related to the problem I'm having and tried to find Disablefullscreen optimizations thinking "hey it's worth a try" but apparently that's a Win10 thing and I couldn't find anything like it in Win7. I tried all the different compatibility settings available in Win7 anyway and nothing made any difference. It did this the first time I started v4 on the first flight I loaded with the Maule. Any words of wisdom from the  v4 veterans?

Thanks, Jim

It seems deleting my previous Nvidia Inspector profile for P3D fixed the problem. I've started the sim a couple times and ALT+Entered back & forth between fullscreen and windowed mode a dozen times without the eyepoint/view going wonky so I'm calling that one sorted. I have no idea what was in that profile that caused the problem, TBH I barely remember making the profile and I'd basically copied what was suggested for FSX using the DX10 fixer pretty much just as an experiment. That took place back in the P3D v2 days, but Prepar3D.exe is Prepar3D.exe to the driver so it treated P3D v4 the same as it treated P3D v2. I had to reinstall Nvidia Inspector to even get rid of it, lol. Anyway, on to the next hurdle!
