Why am I having FPS issues with my current setup?

[arcadiaaaa]

So the games I play mostly are Terraria, TF2, CS, and some other source games. I used to be able to run all of these at 120 fps before, but now it crawls. Terraria usually can't get above 20, and TF2 hovers around 80, and I use a max frames graphics config.
My hardware is as follows: (on a laptop by the way)

Intel Core i7 4800MQ @ 2.70GHz generally runs around 60 degrees

24 GB DDR3 RAM, cant remember how it was configured, probably 2x8 + 2x4

NVIDIA GeForce GTX 765M usually 60+ on high load

stockish motherboard, not a name brand but the model number is W35xSTQ_370ST

I've only checked my drivers thru windows, not sure if I should check more thoroughly. The ventilation is clear, I clean it monthly.
Any other details you need I can definitely provide.
Also if you want to talk to me about it on steam add me here.
Thanks in advance

Are those temps recent numbers or old ones you're guessing at?
Did you change anything?
What does your cpu/gpu usage look like while gaming/idle?
Viruses/malware?

Recent, like I checked while playing those games, using speccy. I haven't changed any parts.
Idle:
CPU 60
GPU 45
MB 60
Gaming:
CPU 70
GPU 65
MB 70
These games shouldn't be that taxing, which is why I'm confused.
Viruses/Malware-wise, I run scans of malwarebytes every so often, anything else you recommend I should do?

You should be able to get drivers from your laptop manufacturer's website as well.

Will do. I'll post if anything changes
