Seriously...
I finally installed Gehn.8.
The work they do under the hood like relaxed splines, disturbed matrices should help the overall quality of the game .
For the old PC issue solved, I cannot really answered since I'm not concerned.
I really like the landing behaviors now. A stand jump results in a stand jump landing. A walk/run-jump results in an appropriate landing. I'm glad I brought this subject to the public place althought it seemed that you were already working on that matter when I did mentionned it on OpenUru.org's forum.
On another matter:
I want to congratulate H'uru team for one BIG thing that should absolutely be moved into Cyan's shard ---> the unlocking of the framerate. I don't know if it's related to Gehn.8...anyway that's not important. On Gehn you can have the fastest PC on earth you have the same jumping/skydiving abilities & ease as for a slower PC. On Cyan's shard there are 2 distinct groups which is really segregationist: those who can, those who can't. Having a quad-core on MOULa is a handicap.
With the graphics & textures quality I have on Gehn, I'm not sure I will ever use my older PC to log in Gehn unless I need 2 avatars at same time. On MOULa, I always feel like I'm playing SuperMarioBros3 if I'm loggin in on my new PC with supposedly "better" graphics, that's a non-sense!
