If you are one of the people who are getting the high CPU usage problems then please read this:
(1) Wait until the problem starts to happen - from what people have said, the only way to get it to stop is to restart your PC, so I am hoping the problem will continue even after restarting FPHG with these new options.
(2) Edit run.bat to look like this:
FreePHG.exe -debug -prof >> fphg.log
Please keep any other options you were using in run.bat also.
(3) Run run.bat using those new settings and wait for the problem to occur again.
(4) After seeing the problem occur again while logging is active, please save a copy of fphg.log, zip it to reduce its size and send it to me: firstname.lastname@example.org
I can't promise I will get to the bottom of this, but this should help me. Also, please don't just run in debug mode all the time, as it will make FPHG slower, and the log files will be huge (too big for me to find the problem...).
