Jumping distance is the same regardless of PC walking or running in 0.45 RCs
In Vanilla and OpenMW 0.44.0, the PC's jumping distance varies by walking or running. Naturally, if jumping from a walking speed, the PC jumps a shorter distance, than if the PC were jumping from a running speed.
In OpenMW 0.45.0 (or at least the RCs for Windows 64-bit, tested on a W7 PC), jumping is that same, and does not vary by movement pace. Speed does not change when tapping or holding the run key. The distance covered in 0.45.0 is the same as the walking-speed jump in 0.44.0. It does not seem to be taking running state into account at all.
I will switch over to Linux and test the Linux 64-bit RCs to see if they are affected as well. EDIT: I tried to download k1ll's Linux RCs, but the links are not working for me. I can't test them as of now.
