You should optimize the mod. Hotline Miami 1 and 2 are normal in my PC and this version is slow. . It seems that Crypto are undermining my PC. He has even crashed because "Out of Memory".
I am playing at 640x480 with colored limit to 16 bits so that it goes better and the difference is noticeable.
Yes, I enable the performance option and I have disabled the another option (which was disabled by default).
I have an i5 with 8 RAM. Maybe an idea. But I find it hard to believe that it is so slow.
