I'm not sure whether this is a RTSS or Starcraft 2 issue, but I'm gonna post it here anyway since Blizzard hasn't acknowledged the issue (yet). Using MSI Afterburner 4.4 + RTSS 7.0 (final), when launching Starcraft 2 (v 4.0.2) it immediately crashes with "An unexpected fatal error occurred". Mind you the 32-bit client launches normally. Took me quite a while to figure out what's the issue. In RTSS Setup under Compatibility poperties, I had to disable "Enable 64 bit applications support service" to make it launch. Alas, with that I can't use the OSD overlay anymore. Will this require a RTSS fix, or is the onus on Blizzard? Thanks in advance.
