[LOW FPS after installing FSUIPC5]

**SOLVE**

After trying and investigating for hours, I found the guilty. My sound config was set to Digital Audio (S/PDIF) and for a unknown reason, and was affect the p3d performance by leaking the frames. I change it to Speakers Hight Def config and everything back to nomal and run freely. 

I still don't know how the pc sound config can affect the fps that way?

[LOW FPS after installing FSUIPC5]

Need assistance.

Brand new machine with P3d v4.5 installed and Win10. I had 25-29 fps (block to 30) and everything ran well. I install a registered copy of FSUIPC5 and then the FPS drop to 5-6. Very frustrating as I just pay a lot of money on hardware to run p3d smooth with add-ons and complex planes...

I did try to remove/reinstall Fsuipc, restart pc: nothing change. 

I notice that when i use the slew mode, the fps show a 'normal' value, but when back to flight mode, It drop to 2-5 fps, even with no AI traffic on a stock airport.

I recall that everything was running smooth with good frames before installing the module
