Normally i used to play dota2 with 60-80 fps but suddenly some few days back, my fps dropped itself to 10-15..i tried uninstalling and reinstalling it too..but its still the same...now my dota 2 lobby is also kind of laggy....i even tried lowering my video settings but its still the same..game runs in 10-15 fps... For normal use lap is working just fine...i mean it doesnt hang or anything....my lap is dell inspiron 5000 series with 8gb ram and 4gb graphic card(AMD Radeon)...Can u please tell me what to do ?
