1) It should be the same, except if the timer didn't work correctly in the Legacy version on your PC, and works correctly now
2) The Tennis.ini doesn't command the display settings anymore, as it's set by the game launcher ; however, the frequency doesn't appear in the launcher, so I'm not sure how it works for it...
Anyway, if you didn't turn V-Sync off, then the framerate should be locked to your monitor refresh rate.
3) Yes, the hiccup was kinda bad ; I tried to smooth it in today's update. It's now almost unnoticeable on my PC (I7@4.6Ghz), but I'm not sure it'll be good enough or not for less powerful PCs...
And I'm glad to know you enjoy the change & the game ! scarecrow
No wind planned for the TE world. It was already painful enough to watch it on RG this last week...
And what do you mean by "max fps" ? And "both games" ?
