Fangames running slow on W10 (after anniversary update)

[FlippyTheYoshi]

Title says all, since I updated W10, any fangame refuses to run smoothly, and instead I get a 10 or less fps while playing.

Yes, I've tried everything on this thread: https://iwannacommunity.com/forum/index.php?topic=2308.0

Studio games however work perfectly, so I'm completely out of ideas after some research.

Any help?

Edit: Tried safe mode, works a bit smoother but not like it should work.

Guess this is yet another reason not to use windows 10

I am having the same problem on windows 10 and I can't play IWKTK 
so +1 for a tech wiz to help fix this

-so i actually fixed it for myself by just running it as admin with no compatibility option derp

So of course I'm experiencing this on my machine with a i5-6600k/1070, but I figured out something stupid. If I open a browser (I use Cyberfox) and point it to a webpage to induce load (Like Reddit) games will suddenly run properly in W10.

Edit: Hmm...

Ok, after trying A LOT of things and many different computers and chatting with Yoyo support I found a workaround.

First of all, this seems to be an issue with Nvidia drivers in Windows 10. Among all the PCs I tested on, the only ones who gave me problems were NVidia on a Windows 10. The same PC running Windows 7, the game runs smooth. 6-year old PC, the game still runs smooth.

So I figured that Game Maker Studio activates some mode on the GPU or uses another method for rendering or something.

If you go to the Graphics tab, under Windows on Global Game Settings, you'll see a section named "Advanced". Check the "Alternate Synchronization Method", create an exe, restart your PC and without opening GM, test it if it runs well now.

Found a fix just run in admin mode (I made a account just to reply to this)
