Thanks for your reply Chris!
Yes, but the client version of steam is the worst (laggiest) option to play RotMG, since there, it's not even possible to set the quality to low.
The best results gave Flash Projector 10 and SWF Opener.
Bummer, have you tried talking with Wild Shadow to see if they'd add in the low level quality to the AIR based version?
I haven't tried it, but they won't add such a function to the AIR version.
Wild Shadow got acquired by another company, Kabam. Kabam purely aims on monetization, and doesn't intend to work on anything that doesn't directly increase their profit... After Kabam started to work on RotMG, every build introduced dozens new bugs to the game. Features that worked perfectly fine before, are now bugged. It gets worse with every new update (build).
Well this was a bit offtopic
But my main point of the topic is that the game performance of the flash projector decreased a lot. So there seems to be something "wrong" with flash projector 11, since projector 10, and that SWF Opener (or other swf player) worked always pretty smooth.
I think creating an improved flash projector version (based on projector 10 and other swf players) would increase the game performance of RotMG and the game would run much smoother on the projector.
