CountMRVHS, can you give more info on your system?

Desktop/laptop?
Which OS?
Amount of RAM?
Graphic card(s)?
Hard drive/SSD?
TWS2: any mods installed?
Graphics settings/unit sizes?

I'm not really a tech guy, but any of the above info might help in narrowing down a search for solutions. And I have no idea regarding Adobe Flash and TWS2.
