Hello Everyone, This is my first thread here I have a mac since 2010 in the time of Snow Leopard and bought parallels 5 with it to play my older pc games. Using vm's of both win2000 and xp i got quite a lot smoothly running and they were reasenable enjoyable. That all changed when i upgraded to 8 and then to 12. I am currently doing test on snow leopard using dualboot with high sierra with PD 8 to see if the same games which were perfectly playable in v5 are this still at v8. However at v12 on high sierra, i notice that the graphics are way off, the games are practically unplayable and the startmenu otherwise stutter in sound of the video overlaps. I haven't changed any setting from on pd version to the other. i don't understand why this is happening. Did anyone have issues with that?
