Iâm no authority on this but:
I sometimes use Chrome (quick jump on and play, daily quest checks), sometimes Flash Projector. Under Chrome I get lag and DCs with urgles, Son of Arachna and pretty much anything with beam type shots. I also get massive lag when itâs busy like in Oryxâs castle, cube gods, that sort of thing. I also get DCs when entering random locations (dungeons, vault, etc.).
As far as I can tell by the symptoms there is a (software enforced) limit on the amount of packets Flash is allowed either send and/or receive. Iâve tried both wired and wireless on different hardware with the same results.
This is annoying as the game runs much smoother (frame rate) in a browser the projector.
Sadly, Flash Projector isnât available for ARM (Cortex) on linux.
tl;dr
Realm in browser bad but since thereâs no ARM Flash Projector for linux youâre out of luck.
