Turn off experimental RenderItemCollection, as although it reduces Gen 0 and Gen 1 GCs, it makes little difference overall and currently leaks some memory. You can turn it back on with the #define at the top of RenderFrame.cs.
DataLogger has been updated to match F5 DEBUG better; specifically, it now logs memory, managed memory and GC collections.
Added new boolean option "DataLogger" to enable starting with it logging; use /datalogger command-line option for this.
