The first release of 127 based r3dfox. Since 127 is still technically beta, this is considered a RC release. This is also somewhat in progress.
Base 7 SP1, and RTM support is back! If you're using RTM, you need to install the VC++ 2019/2022 redistributable, and copy the appropriate files from the r3dfox-7-RTM-fix.7z to the r3dfox installation directory, and it should work.
I think the only other change since 126.0.1 is the fullscreen transition fix. (Thanks @bbc-chi)
Oh I almost forgot, it should have Aero on 10 by default if you have some sort of Aero thing. Not sure how the compatibility is though.
Since it's not a full stable release, it's x64 only.
Haven't tested on XP (extended kernel) nor have I extensively stability tested. I have started to test on Vista (Extended Kernel) again though, and it seems to work fine enough there.
Please let me know what bugs or issues you encounter with it.
