@siddhartha said in Windows 10 creators update - Youtube slow in opera with hardware acceleration activated:

I found what might be the problem. In W10 FCU there is a new Exploit protection enabled by default. This is CFG (Control Flow Guard). When I turn it off (just for opera.exe) performance improves significantly. Seems on older computers it affects the performance more than expected.
If you experience the same. Open Windows Defender, go to App & Browser control / Exploit protection settings and turn off CFG for the system or add an exception just for opera.exe (or other degraded program) from the Program settings tab.

Good to know that.
Corroborate it after some testing time and let us know if it's fixed for future cases.
