In the last stage where you have to plant the bomb to get the holodrive out via the helicopter,
in that stage’s location, where the defending them have to go through to defend, depending on where you look there is a bug of FPS drop.
If you type ‘stat unit’ you will see that Game Thread is 4ms, Draw Thread is 14ms (which I guess makes the FPS drop), and GPU is 6ms.
So something is wrong there.
Now, I tested this on DirectX 11, on super settings with blur option off.
