--- Comment #5 from krzysio.kurek at wp dot pl --- Created attachment 42199 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=42199&action=edit callgrind output I can make the program output to console average fps after 20 iterations with 10 warmup cycles. The program will still run with GUI, but will output just FPS to the console and exit. Will this be sufficient? I'm a complete newbie to the whole language, but I got some profiling done. I'm attaching callgrind output files, they're named after which compiler was used.
