Idk if this is common knowledge but I thought this was an interesting take on level 3. Obviously not as fast as the floor clip but seems faster than the tree, so could be a nice medium for people who want something a little more consistent than the clip. As most things in this game the climb is a little fidgety.

In the video you can see with smooth panning the mouse seems to jump forward a bit. Either that or it's freezing momentarily... Makes it impossible to play and is endlessly frustrating. I am using GoldSrc 2.1. Both -noforcemparms and -RInput are in the .bat so I'm pretty sure it doesn't have anything to do with mouse acceleration. I was watching the FPS in the top corner and it seems to be dipping for some reason and I think it may have something to do with the stuttering. It is set to fps_max 100 and my CPU is definitely not maxing out so I have no idea why that would be changing. I tried in windowed mode and I'm getting the same results.

This post seems to have the exact same issue I do but has no responses... https://www.speedrun.com/hl1/thread/1wxzv

What I'm talking about is demonstrated here (at 1:07):

I believe the hammer has to get stuck in one of the notches in the wall, but getting it to get stuck is very difficult and the physics there are extremely fidgety. And also, once it gets stuck, how should the mouse be moved so that the character's head reaches the goal? It feels like where the mouse is moved and where the head goes is not always the same.

So is there some way to do this easily that I'm missing?

I haven't found any rules that specify which NES emulator to use, so I assume they are all ok. If someone could confirm this for me that would be great. I was also curious if we need to submit anything else with the run for proper verification when the run was on emulator.
