For the forum, the test version does indeed appear to work in 64bit as well as it does in 32-bit mode. Fantastic, thanks!
We need to compile a list of the rF2 data feeds that appear to work though - I might try an initial list next week (bit of time on my hands...) as obviously not everything is supported and I can't currently work out if the feeds are broken or just not there. For instance, the Imperial-units fuel measurement is incorrect/unintuitive (both 32/64 bit versions) as far as I can tell (doesn't match either US gallons - or UK gallons. 10 USG comes out at '140' magical units). Metric fuel is fine. Some of the timing info. is present, some not.
Really appreciate what has been achieved so far though
