Another good day so far of testing and tweaking, mostly playing detective with some rogue memory leaks. The biggest and best news from me is that I managed to reduce the start-up system memory usage by 190MB bringing it down to just 430MB with full terrain system. We also made some good strides on the store and also some key crash fixes which we found during extensive testing. Cannot do a big blog as I need to get right back in it. I am currently stepping through the test game in/out process to find out why it can leak anything from 500Kb to 65MB after a single test game session. This work has already yielded a fix which prevents anything greater than 4MB from being allocated during the test game set-up (at least the DIM stuff), and is just a case of tracking as much of this stuff as possible in the time remaining. All in all, progress goes well!
