APITrace 3.0 works fine with Wine, but the performance hit is huge and resulting trace size seems to be non-manageable. Trace file containing two frames displayed at the game login screen is ~2GB in size, and non-surprisingly game performance is more like "one frame per twenty seconds". With oprofile I hit another trouble - it seems that this tool is unable to fetch symbols from libGL, at least all I get in reports related to libGL are simple references to /usr/lib/libGL.so.295.40, /usr/lib/libnvidia-glcore.so.295.40 and /usr/lib/tls/libnvidia-tls.so.295.40 without any details available on symbols that are internal to this libs. It might be me misusing oprofile although, as currently it is the first time ever I'm trying to use it to do profiling tasks. - -- Best regards, Alexey Loukianov mailto:[email protected] System Engineer, Mob.:+7(926)218-1320 *nix Specialist
