The game ran very smoothly and fast on all my computers. (AMD Phenom II x4, AMD Ryzen 5, Celeron 4100, Xeon etc.), Windows 10 and Windows 7, Chrome 91 and Mozilla 89. Profiler says, that the “test” version works even a little faster (just a little, maybe due to AD).
BUT! I finally managed to find a machine, where “test” version always works MUCH slower, than “good” version. This is an old machine with Windows XP (it can run Windows 10 x64, but for the tasks that machine performs, XP is more suitable). And yep, it is AMD.
“good” version also works not so fast (it’s ok for this computer!), but playable. For example, first game (crescent) start animation lasts 40 seconds, then playing quite comfortably. “test” version same animation lasts aboud 120+ seconds and it’s much harder to play.
Machine specs: Asrock E350M1 with
CPU: AMD Dual-Core E-350 1600 MHz
RAM: 4096 MB DDR3-1333
VGA: AMD Radeon HD 6310
OS: Windows XP SP3 x86
Browser: Chrome 49.0
Yes, machine, OS, browser - everything is old, but i think it would be the same behaviour in new OS and browser on this machine, and the fact remains - the new version of OpenFL/Lime/Haxe runs noticeably slower on some machines, no doubts.
This is not my computer, but I often have access to it, so I’m ready to take part in any experiments to find a problem
