I have spent the last 2 weeks trying to get FSX to run great on my machine, This has involved many reformats due to files and registry stuff(REX) messing up reinstalls. so I have had to reformat and re-download FSX many many times since there is no good way to back up the game(tried steam backup and backing up the base game folders to external hard drive) I think I am up to 8 times I have done this in the last 2 weeks.

 

The last 2 tries have started to irritate me as any time I click anywhere on the screen in game, I get lag for a few seconds before the game resumes, and then there is the huge lag when trying to access display settings from the drop down menu in game to the point where it just freezes on me.

 

Right now, I have downloaded and reinstalled the game after my last reformat from 3 days ago and tried the game and it still happens. Any ideas on how to fix this?

 

Right now I have not tried any tweaks or installed any addons. My system info in my profile is current as well.

I think I have fixed it.

 

had Shadowplay capture desktop enabled, disabled it and the click lag went away as well as the menu stuff freezing.

 

Strange thing is, I have use that option in the past with no problems.
