BOOTP: The original game should look sharp and detailed with all the options maxed out.

With sofplus installed, these are the in-game video settings I am using which I believe were the highest options from back in the day:

Also, make sure you tweak the 3D settings for your graphics card. 8x antialiasing seems to work fine but I turned off any transparency (supersampling) because it causes text corruption.

I am currently running at 1920x1080. You can run in 4K, but the HUD becomes so small it is unreadable, at least on my VDU.

On another note, EAX works fine with Creative ALchemy, but I noticed setting anything higher than 22KHz with EAX simply reverts back to 22KHz when reloading the game. This only happens for EAX and might well be normal behaviour, but I cannot remember.
