Problems on XP

[2017 MacBook Pro gaming]

Hi guise.
Yesterday I downgraded my machine from windows 8 to windows XP. (A 90's game had SERIOUS problems. Even compatibility mode didn't work.)

On windows 8, CS:S ran good, I didn't get veeery much FPS but I could play the game.
Now, the LIGHTS are too strong, and game doesn't run higher than 5 FPS. (On 8 idk it was atleast 16 or 17. but mostly at 23 or so)
My computer has 1,7 GhZ intel atom and 1 GB of RAM.

There are also a lot of FPS configs on the world wide web.. I tought there was a good one at the ESL website, but I'm not for sure...
