Thanks for responding guys!Based on what i know i doubt that SC2 has any anti repeat delay/rate changing or anti macro feature though. I know of certain casual players that use macros without any problems while playing SC2, a terran friend of mine has a macro for making a ton of marines by just one button click and he has used this for quite some time now. Macros are strictly forbidden in SC2 (stated very clearly by Blizzard) so a non casual SC2 player would never consider using a macro for anything in SC2, and that obv includes myself. And thus, we are obv never seeing a serious player showing up at a lan event with some macro functions to make use of, because that player would be disqualified in an instance. But based on what i know it seems macros work perfectly fine in SC2, and for casuals it seems to be more commonly used than one would think. Also i know that players have been able to play SC2 with a way higher repeat rate than the windows control panel max when using a keyboard with options for increased repeat rates, such as the Zowie Celeritas. But Keyboad King and FilterKeys (not macro software, just repeat delay/rate tweaking) as stated dont work well at all with SC2, while macro softwares seemingly work just fine. So i dont think the reason as for why Keyboard King and FilterKeys dont work too well with SC2 has to do with some purposely made anti repeat delay/rate tweaking or anti macro feature by Blizzard, but that it instead has do to with some programming conflict between the program and the software.Obviously an increased repeat rate or a lowered repeat delay is not a macro by any means, but since it can give an edge it is reasonable to question whether it should be allowed or not. I came across a post in a blizzard forum asking about tweaking repeat rate/delay values beyond the windows control panel ( http://us.battle.net/sc2/en/forum/topic/2794772806 ) but he got no response by Blizzard. Blizzard has stated very clearly that macros are not allowed, but on the matter of tweaking repeat delay/rate it seems they have been silent. But not too many people have been asking about it anyways.In any case, i am still interested in getting FilterKeys or some other repeat delay/rate tweaking software to work for SC2 so if anyone here figures anything out let me know. What i would change is basically just lowering the repeat delay from 250 ms to about 120 ms (it cant be too low because that would make it so that i would double click control groups and other things by mistake). That would make it so that i would save significant time troughout a game when combining all the small moments where i save time. The repeat rate max in the control panel can stay the same as i dont find it as vital. But yea, lowering repeat delay also has its downsides, thats why one can select different levels of it in the control panel anyways.
