Interesting. My experience differed quite a lot, for example Gabriel Knight 3 was almost impossible to get running, and when it finally worked it was lagging as hell.Gabriel Knight 2 had it's aspect ratios all over the place, it often switched to stretched after a cut scene, I found no fix for it online. The other one I tried was Realms of the Haunting, and it worked great until I reached the tower. From this point on it crashed every few minutes.
