Howdy mate,
If you're willing to start up a teamviewer session I can probably help you out remotely,
The only thing I can think of is a process running that conflicts with the game but that's all I can think of right now until I actually get a closer look at what you have installed on your computer and what processes are running.
If you dont want to start a teamviewer session then just take a screenshot of your Task Manager Process Tab and post it here so I can see the processes.
I am always willing to try and help others and I think I might be able to help you to get it sorted out so reply with a yes or no (If no then just post the screenshot)
