sorry, and i understand.
I dont know how to reduce fps drops when "players use ui in game".
And question is what we can do to repair or reduce this. We personally have no ideas. Such symptoms appear on every other graphics engine, starting with directx, etc.
The game is writed in C++ with SDK 10.0 on visual studio 2017 (I don't know if it's important)
if you need more something please tell me.
