i set motion blur to 20x, and it worked fine for a while (was very laggy, no doubt), until the game froze for a few seconds then my screen blacked and went bsod. I'm geussing motion blur ate up all the vram or something?
Driver or hardware issue.
For me, in 99.3 with moBlur on Construct crashes if I go to the next layout.
Develop games in your browser. Powerful, performant & highly capable.
Application level programs (like Construct) cannot cause BSODs. Only lower-level things like drivers can cause that. So try updating your graphics card drivers.
strange, I have Nvidia's latest drivers. (8300 GS)
Maybe part of Windows, your hardware, or another driver is breaking.
