i have intel Q6600 2.4Ghz with 4Gb RAM DDR2 Graphic card is:- Geforce GT1030 on Windows 10 64bit i play 2K or 4K YouTube video and it run's smooth like butter even on 8K@60fps is run's smooth. !!!!!
but on Lubuntu 64bit 17.10 on Youtube 2K video and 4K video have very high CPU usage. and it's lagging. how do i use my GPU? when i use Windows 10 the CPU usage is 20% to 30% but when i switch to Linux its 100% and lagging.
