Hey,
I had fps issues with plugin so i was thinking.
As i know the current method is copying the bytes two times from the vram -> ram and ram -> vram. (It is very inefficient way i think and thats why my fps goes around 10-20 if i have a full screen webpage opened.)
So i was thinking, is it possible to edit the plugin and share the texture pointer? So unreal engine can use the rendered texture directly without copying the bytes from the graphics card to the ram from QtWebKit.? I am asking it because i am new in Unreal Engine 4 also i have not that much experience with directx and Qt. But i know opengl.
And if its possible i might give it a try and implement it.
