My many thanks to all of you trying to help me. There is many hints but I'll try to answer them globally at once there: - I tried to avoid clip-path and it is as one game option to disable. It helps a bit, but not much. My clipping path is done using two primitives - circles; - about javascript itself, I believe it runs quite fast; to maximize game speed I'm keeping all the information in script and during gameplay I minimized impact to write only, there are no read operation - about CPU usage => I'd say yes, I also prefer the way of Firefox => get maximum of CPU and do it as fast as possible, than behavior of Opera which is visually slower than could be, but taking not more than 60-70% of CPU - about the cycles, in general there are very different number of setTimeout cycles during the game play. But during debugging, there is only one (or two) cycles. This only one takes almost nothing (3%CPU) and the only action after keyDown is create the event, send it to listener and listener will change global property. Then, still running cyclus will do transform/translate of group. It is everything. What e bit complicates the situation is, that event keydown is repeated when key is holding, but this is something I cannot avoid (I think) and everything else is spent on translating the group - about CSS / attributes usage (and that are the same in Mozilla) => yes, but they are helping other viewers so I don't plan to change it - I read about performance boost on FFX nightbuilts on paths and gradients and tried it, but in general it performs very differently from week to week and latest ones have even temporarily broken clip-path support and perform slower than latest releases (but yes, there were also faster ones some three weeks or so back). I believe it will be cool in the future of FFX3 - about different viewers => I like them all and I'm trying to make game as compatible as possible, but I've to power to try also Corel or Renesis implementation before game will be at least at 1.0 - if there is somebody else in this group to help me with betatesting/code-inspection (yes, in some of you already am in contact), please contact me at marek(dot)raida(at)vodafone(dot)com and I could send you current code with belief, that with a little help with few of you I'll be able to finish my work and then publish it freely to the nice SVG World of many fans...
Thank you all for your patience with me...
