I think there is some FPS leak caused by the HUD visualization. Because disabling the HUD entirely ('Backspace' key by default) saves for me about 30 frames...

So, when I have 85 frames with a full HUD active - disabling the HUD entirely shows on screen more than 115 frames :O ... It even does not matter if the UI EFFECTS are off or on or enhanced - all the same ...

I checked the vanilla remastered game for that problem and found no any FPS issues there... Disabling the HUD there makes almost no increase in frames (about 1 or 2 frames!). So, there I have about 250 FPS with a full HUD and 252 FPS without it...

Beghins, please recheck the HUD issue - it causes enormous frames leak for shure...
