Thank you for helping me regarding my Problem, i bough a chinese Haeir X3 Pro Laptop when i was in china:
Core i5-4210M 2.6GHZ
Nvidia Optimus GT840
4Gigs of Ram DDR3
The laptop came equipped with win7 Chinese version i removed it and installed win7 US version, tested it's performance played DOTA 2 games with MAX settings and 60FPS and everything was going fine until i decided to upgrade to win10, after clean install i installed all the required drivers, and then went to test it's performance in a DOTA 2 game, i put MAX settings as usaully and then tried to play the game ran with 5-10FPS, tried many games all run on very low with sluggish performance, Device Manager Detects GT-840 Nvidia Optimus Signal that the game is runing on high performance GPU, but i think it doesn't.
What i tried:
- Reinstalling Win10
- Reinstalling Drivers.
- Downgraded Intel Drivers as suggested in one of the forums.
The Strange thing which made me wonder more is that, nvidia Geforce Experience Detect that the GPU is 840M but doesn't enable the battery boost feature for the following reason (check pic)
