Game Startup problems
ReFoce adds game required start resolution to Windows registry. Even that Your monitor does not anymore support 800x600@60Hz resolution (e.g. Battlefield 2 starts first to this resolution before logo videos), some games needs this resolution for a quick few seconds.

Try to start the game without touching your keyboard or mouse intervention. Some games get to trouble when loosing focus, e.g. quite-old CounterStrike HL1.6-steam and quite-new Dead Island.
