I 've just completed the mission. I play TDM on a 10 year old PC with Nvidia 8600GT on Linux, it's definitely a low-end PC now. The outside of the manor I liked very much, but nothing special in the interior. The graphics was a bit slow outside , but OK inside. The game did not crash at once on Linux, which I experience with some rare TDM missions in the past. This is positive too. I struggled a lot to find the secret switch in the dining room, I had to check this forum for some hints . It was also hard to get pass the guard in the lobby, I couldn't do it without a noisemaker arrow . The bug regarding the stewart and his key dropping was very annoying, but I guess you will fix that somehow NeonsStyle. I can't wait for V-Man's "Stealth score = 0" video on youtube for this mission
