Thank you for information. I guess the best solution, upgrade my PC. But now prices go up to x2.5-3 and will stay at this point for a long period.
Maybe a low resolution will solve some problems, but right now main window set at 4K display (in-game 1080p, main @50/60 fps and slaves @25/30), everything is fine except font. And if i'll set a low resolution, i'll get bad font.

Maybe i'll do some trick like i did with WoW)

About classes, I think i'll sit at Hawkeye's for a bit, i really enjoyed them.)
