Elysian Shadows

So as the title sais, when i use timers, to regulate my FPS on my game, as soon as i start moving my mouse, aver the aplication, it starts lagging, i tired to disable the Threded optimization on the Nvidia control panel, but still nothing, any suggestions???

I actually remember having this exact issue quite a while back when developing in SDL. Never did come up with good solution, but I would imagine if you threaded your event handling separately from your rendering it would solve the problem.
