FPS Lag

Hey Z8games community,

I have some FPS problems in crossfire on my laptop. I get from 15 to 30 FPS max in a public
game and I get from 25 to 50 FPS max on 1 vs 1 game. my laptop specifications :

Laptop's Name : Dell inspiron 1525.
OS: Windows 10 64-bit .
Processor: Intel(R) core(TM) 2 duo CPU T5800 @ 2.00Ghz.
Ram: 2 GB.
Graphics card : Mobile Intel(R) 965 Express Chipset Family (Microsoft corporation - WDDM 1.1)

Note : I know that these specs are not good at all , I bought this laptop from 6 yrs but I am only asking if there is a chance to get a good FPS ...Also when I open CF like 1 hour or 30 min my laptop shutdown by it self ( I think that it is Overheating problem but it only happens when I open any version of crossfire ) .... Thanks
