The recommended specs end up placing you in the medium range. The reason your fps drops is because you are trying to load so many models with high textures. The really only way to fix it is to upgrade(Which you cant, laptop) or lower settings.
What do you mean medium range? Systemrequirement labs tell me I exceed recommended settings already....
Strange. 2 years ago when I bought the laptop the game seemed to run smooth without any fpsconfigs or the likes, recently I did a clean install of windows and got all my backup stuff as well. The game is unplayable without a fps config and it's still a bit laggy when tons of stuff is going on with an fps config . I wonder if it really is my laptop, or if tf2 is just really unoptimized like many users say it is
Don't have any heating issues either, laptop stays pretty warm while playing tf2, never hot or overheating.
