Sorry, just one last thing. Is there anyone who can shed some light on whether or not I can tick the box "Disable fullscreen optimizations" in the avast properties?
https://imgur.com/0xK7RRt Here is a pic of what I am referring too. It will not save the option whenever I try to hit apply sadly. In fact, I can't change anything here.
The simple answer is NO you can't make any of those changes.
Dang. Alright thank you.
I hope this changes in the future. Being able to disable fullscreen optimizations like that is actually very important to improve gaming performance.
Improve gaming how?
In windows 10. Fullscreen Optimizations has been known to cause tons of issues with gaming performance since (I think) 1709. You used to be able to turn it off globally in various ways, but since 1809, it seems to be that you can't disable it on a global scale in the system anymore. (Some say you can, others say you can't, it is it or miss).
Many places I have read said that disabling it through the properties section (in the screenshot I posted) does work however, the annoying part is you need to disable it for each program 1 by 1. The problem however is a lot of people also say it isn't just disabling it in games. So long as something running in the back round is being effecting by fullscreen optimizations (for example: Nvidia Control Panel, Discord, Cortana, even something simple like Notepad etc...) , you need to disable it because they too can effect whatever you are doing because of fullscreen optimizations trying to do... Well whatever it is that it does to whatever program it is trying to optimize. Some have also said it does not matter if the program is actually open on the desktop, as long as it runs in the backround, fullscreen optimization is trying to do... Again, whatever it is that it does. I assume that Avast is one of these programs because it has the option, it just doesn't let you.
Take what I say with a grain of salt here of course as I am, like many, just some random person on the internet. I've just read a ton into this issue over the past couple of weeks.
