Maybe I'll call the flame now, but IMHO I don't think Unity is a good system (like everything from MIcrosoft). About a year ago, I tried to write a graphics-intensive application in full-screen mode and compared the speed of code in #C and Java. Unfortunately, Java outperformed #C by a few horsepower in terms of graphics performance and acceleration. If Unity is written in a similar way like #C, I'm not surprised by the current problems with graphics, speed, rendering distance, etc ... The best way is to write an application (game) directly in C ++ code and use direct access to DirectX, any intermediate layer (like Unity) only steals computing power at the expense of multiplatformity and other nonsense ...
