I updated this found a fix if you have any of these dracula games and the screen is flickering try
this it worked for me today after i asked for help lol was so lame and simple fix too..

right click your desktop and go to setings for the video change the 32 bit color to 16 and poof screen flickering stoped on the video for Dracula the resurection.....

also on the dracula the resurection use compatablity set to 640 screen resolution too.

It may help any old game using 16 bit color so try it when done playing game just set color back to 32 bit

Hope this workd for you guys it was so simple i couldnt beleave it haha
