Couple fixes and minor changes:
-Top speed shootout leaderboard was showing top 10 from Steam and top 10 from non-Steam combined into one list by mistake. This left out everyone on Steam who was below #10. If it looked like your results should put you somewhere in slots #11-#20 but it didn't show up, this should be fixed now and any run you made before this that was missing should show up now.
Related note: The first time you run the top speed shootout it can sometimes show two leaderboards overlaid on top of each other, one from Steam and the other from the old website version that had its own leaderboard system. Haven't figured that one out yet, but if you see both, it'll most likely only be on the first run after starting the simulator. After that it should display correctly.
-Vee bottom pad height can now be changed in smaller increments (1/8 inch instead of 1/4). Extra digit added to the UI.
-Optimization for slightly higher rendering performance
-Tunnel boat shadows reworked. Cockpit/cell shadows and more complete self shadowing of the boat in exterior view added.
-MSVC 2015 runtimes added which will make it go through a "starting for the first time" process once. This might fix the problem a very small handful of Windows 10 users had starting the game.
