we share the same problem i also have low pc specs and graphics, what i did is use all my core from msconfig, defrag, changed my usable ram (forgot how to do that) changed my keyboard settings to 0 repeats for not freezing your screen while doing fast keystrokes, used antilag v9 with +0 item effect, dont put too much icons at your desktop and dont use any themes, i have nvidia geforce 620m/intelR 3000 4gb ram core i3, i bet this will work well for you, i cant go on mass pk since i cant help any lags from my laptop but for 1 on 1 it works good enough
