I have Win 8.1 64-Bit with 16 GB RAM and a AMD R9 with 4 GB VRAM - and SilentHinter(1) is running perfectly in the
"DosBox". It is still a superb subsim, better than SH4 (exept graphics, o.k. that is old DOS stuff). So for me in decending order it's SilentHunterIII, SilentHunter (1), SilentHunter2. ...
