Huge FPS drops while playing (Minimizing helps)

Hello, I bought myself a new laptop about a month ago. It's been running very well in gaming and still is. But since 2-3 days i've been facing some annoying problem. When i play, say, Watch Dogs, my usual fps is 45-50 on medium. Then all of a sudden it drops to 8-13. I've tried lowering the graphics to the very minimum, but the fps is absolutely the same. What was interesting : A simple Alt+tab and then opening it again fixes it for some time untill it decides to pop up again. It's getting kinda annoying to keep doing that so i'll eventually need a solution.
So far i've tried some stuff found on the internet yet no helped:
Updated RealTek drivers, disabling hardware accelaration.
I downloaded a program called CPU Thermometer to see if the heat is the problem. The values are rather high, yet i've seen even higher. They show about 82-4 C at maximum dropping to 42-3 when not playing and just surfing.
I'll post my specs if it's of any help:
Asus laptop:
Gtx 850m
i7-47100HQ 4x2,5(3,5)
4GB ram
7200 RPS 1TB HDD without any SSD
Hope any of you had faced the same problem and managed to solve it.
Sorry for any mistakes i've made as English is not my mother language and thanks in advance!

Thanks in advance :)

you should have some options under the battery/power section that have to do with cooling. you can look to see if you can set it to maximum cooling so that your laptop cpu fan and gpu fan stay at their highest levels when they are being used. you could also play around with the performance tab to see if changing between low power, balanced, or maximum performance keeps your laptop cool enough to combat the thermal throttling.

whats going on is your 850m is detecting that its getting hot, 82-84c, so it dynamically lowers its performance to help bring temperatures down. this is good since it is protecting itself and doing what it is supposed to do, but bad for you and gaming because your fps fall through the floor. the only real way to stop this is to somehow limit how much heat the gpu and cpu put off altogether by finding a good balance between performance and heat output. otherwise the obvious is to make sure when gaming your laptop has plenty of airflow and that none of the fan intake ports are blocked. many resort to laptop cooling pads that have extra fans help keep everything cool.

Im sorry, i might;ve not been clear. 82-4 is the CPU temp, I don't know the GPU temp.
Thanks anyways I'll try to find a way to check the gpu temp and post it, see if it can help~


Edit: I downloaded a program to check my gpu temp and turned on Watch Dogs again, but did not play long enough for it to fully heat because i;m tired :D The temp shown was 51 C which leads me thinking that fully heated it won't exceed 65 which seems normal to me, but i'll let the pro;s do the work :p

2nd Edit: When i finally had time to play and i opened the GPUtemp file. So i played long enough for the lag to appear, minimized and saw 67C as the temp on my GPU. Strange thing is when i switched to the game again i was still laggy and had to restart the game. I'm starting to think it's some virus, even though i actually did run a scan without anything problematic.
