😳 Unstable FPS on Crossfire

Hi everyone,
Im a Crossfire player from Indonesia. I have problem with my fps. 2 Months ago my fps run good at 40-70 ( well maybe its low on ur opinion but on my computer its smooth enough ), sadly after 2 weeks playing i reinstalled my Windows. After that i only got 10-30 fps. I already try everything like using Gamebooster, change the Crossfire font, use CCleaner, Defrag my hdd, but the fps still unstable, sometimes it drop to 3-5 fps for half minute. Btw i use laptop with Dual Core Processor 2.0 Ghz, ATI Radeon 4370 512 Mb, and 2 Gb of RAM. Some ppl said that i must buy gaming pc. But why before i reinstalled the Windows i can playing it with enough fps? i alr make the same configuration on my system like the old one. And my ping is quite stable. If any of you have solution, please posted here. Thank You

You need to buy a better pc,or upgrade the one you have.
@ gb ram isnt really enough and a little better graphics card.

the fps on CF lately has been a little sloppy, i usually get 180+ but now i get 120 with drops down to 10

Gaming pc for this!

This game was(is) one of the most populated game, because it didn't require a strong pc to run now it is getting more demanding, but i don't you need to spend too $$ unless you are planning for Battlefield games, or other such games!
