The bug exhibited there is a Q2 physics bug. It is NOT caused by R1Q2 server, it is caused by this code that is in every Q2 client/server. if (pml.velocity[2] < -200) { pm->s.pm_flags |= PMF_TIME_LAND; // don't allow another jump for a little while if (pml.velocity[2] < -400) pm->s.pm_time = 25; els...

Do you think you could record a demo of what it should look like and what happens on an r1q2 server? That would give me something to work with.

i have to say, that im having a problem with strafing decently on the servers with r1ch installed, where i dont have any problems with strafing on servers without r1ch. I find this rather strange because nothing is altered on the server which would cause different player movement (PMove function is...

Then when the server gets a chunk of CPU time all the pending packets rush in at once, hence why the R1Q2 server kicks you as it think it is being flooded. To fix this, simply set the server as a high ...
