Now I need to know your desktop specs, what counts as potato to you?

The FPS numbers seem right, try mastercoms low, disable team hud, use nohats mod

What are temps like when playing? Is it boosting to the proper turbo speed?

CPU: Intel Core2 Quad Q6600/ GPU: Geforce 210/ 3.19gb RAM

in game max temps are :
Core0: 98°C
Core1 :91°C
Core2 :90°C
Core3 :76°C
I thought 98 was too much until i made research and found that i7 4thgen MQ can go max 100 on laptops and is normal

did you get a w540?

my w540 runs in to problems with thermal throttling if I run tf2 on it :(

Assuming its an old laptop you got second hand, best you can do is open it up and clear out all the fans + reapply thermal paste. If your temps are still high I'd recommend underclocking, thermal throttling in my experience makes the game run incredibly jank. Lowering your max framerate might also help with temps.

wait how did u know XD it's a lenovo thinkpad w541
I might clean it and change the thermal paste cuz it's a 2015 laptop
Also it might seem high but as i said it's still on the average/normal temp in games, everything is cool when m not playing (41°C - 49°C)

98 is very high, max operating temp is 100 and it'll thermal throttle to keep it below that point.

TF2 is a source game which means it cares more about single-core performance than most other games (esp since lol 2007) but having a good GPU does matter. I'm no Setsul but I do not think it will get much better for you unless you opt for using a toaster cfg. I also had stuttering on my gaming laptop because it came with a 5400RPM HDD in it and when I swapped it out for the Samsung 860 EVO SSD that went away.

I would absolutely open it up and replace the thermal paste though before you try anything.

dunno man, this i7 4th MQ is known to be the hotest so, i just looked and found that it's max can go to 100 and can handle it well, also the only problem i get is some stutter when i turn around in game, otherwise having 60fps with no stutter isn't a problem for me since i used to play on 30fps, undervolting will maybe reduce about 5°c and reduce performance which in my opinion isn't worth it

I'll try replace thermal paste in the upcoming months, cheers for the suggestion !

My w540 with a 4800MQ had exactly this issue running at the same temps because of thermal throttling. Check on hwinfo or whatever to see if thermal throttling is happening. If it is, your PC would run faster but refuses to because it could cause damage to your cpu. Having a consistent processor speed that doesn't need to thermal throttle, even if you have lower fps, will feel way better.

Highlighted some problems for you.

The explanation

Laptops inherently run hot and slower largely due to the extra heat. The primary issue is that a laptop can't dissipate that heat as fast as a desktop can because the components are smashed in together, covered in plastic and have shitty fans.
CPUs the like Intel i7 4810MQ will throttle themselves when they reach their max operating temperature in order to not get to hot and completely fail, it will keep throttling itself more and more so long as it's operating near it's max operating temperature.

There could be a few more things going on but thermal throttling is definitely going to be your primary issue.

The Solution(s)

fps_max 121 // fps_max should be set for laptops to avoid excess heat especially when it's not necessary. Use a lower value if needed.

setting fps_max to 121 should keep your CPU from getting hot in situations where you would normally have over 121fps such as at spawn, meaning your CPU should be a bit cooler on average and delaying thermal throttling and potentially resolving thermal throttling sooner than normal. You may need to use an even lower value.

Get a laptop cooling pad, as it's name implies it should help your laptop dissipate heat faster meaning your should have lower overall system temps, and should mean you thermal throttle less often and not to the same extreme. (I still recommend setting fps_max if you do this)

fps_max 121 // fps_max should be set for laptops to avoid excess heat especially when it's not necessary. Use a lower value if needed.

damn never thought comanglia himself will get in here XD thanks a lot for the explanation it made it clear for me, i'll try the fpx max and see how it goes

FYI it should start throttling at 90°C.
At 100°C it'll instantly shut off to not catch fire/melt. That is not a normal operating temperature, it's the absolute maximum temperature which you should never reach, let alone exceed because that would mean all protection mechanisms have failed.
