Disabling "Hardware accelerated GPU Scheduling" in Windows 10 have removed the stutter or micro-freezes that I was having every now and then when looking around.
I also did a full repair of DCS that removed a file, I believe inserted in there by the Tobii software, called "headtracker.dll). That did not fix the problem but made it better.
Thanks you so much to all of you who tried to help, really appreciate it
Now it comes the pain, repeating the in-game trainings over and over until I have a hand of the A/F 18C. Today I landed successfully again on my 1st attempt (it was a shitty landing but I did not die xD).
Not a youth here so not sure, but I am not bragging about anything. Having better or worse hardware means nothing. Everyone have their own personal circumstances and priorities. How was I supposed to ask for help fixing a performance issue without mentioning the hardware?
