Hey,

Glad I was of some help with this. I did try an old NI profile first which sorted it. But there was so many settings changed it wasn't clear which one was the key, so I started fresh with NCP.

Go have some fun simulating.

Hello again. Forgot to mention that setting 'Antialiasing - Setting' to SLI 8x in NCP did not work. I had to set it to SLI 16x, probably because I have 'Texture Filtering:' in the sim set at 'Anisotropic 16x'. Don't know if this is relevant but thought it worth a mention. Here's a screen shot. http:...

Hey Guys. Using v4.0.28.21686 Professional, I have also had this same problem with UN-docked windows. So today I thought I would see if I could track it down. Long story short is yes. I found my problem. First thing I did was disable SLI and reset everything to default values in NVIDIA Control Panel...

Yes. A 'Client' only update to v3.4.22.19868 with a non-clean install of Nvidia drivers 378.49 and all is well again in SLI mode.

The only stable combination for me at present is to use P3D v3.4.14.18870 and nVidia drivers 373.06. All drivers after this results in flashing effects and menu's, even with P3D v3.4.18.19475. Interestingly, the v3.4.18.19475 and 373.06 combination also results in the same flashing problem. Cheers. ...
