How to apply the jumpy mouse camera fix patch to WotLK

[Shred]

There has been some interest in this patch recently. The patch is distributed as an already-playable game executable but there are some people who already have patches applied to their executable to fix other bugs and would like to keep those patches too. This is the link but I can't give credit because I don't know who the original author is. https://mega.nz/folder/ykZglR6J#LOG-hGTqJ3ZOTROwTlG5Hw

Download HxD, which is an editor that you will use to apply the patch: https://mh-nexus.de/en/hxd/. Then open the wow executable using that editor. You have to close the game first.

The following table presents an offset (the offset is the number of bytes where the original code starts, counting from the beginning of the file), the original code that will be there, and the code that you have to replace it with. You have to apply all of these modifications, one by one. To apply one:
1) Press Ctrl+G to open the "Go to" dialog and paste the offset. Your cursor will be positioned right before the original code.
2) Select all the original code making sure it's the same as presented here.
3) Copy and paste the patched code on top of it. If, when pasting, you get a dialog that says "This operation changes the file-size.", you didn't select the correct amount of bytes. Press Cancel and go back to 2.
Do this for every row of the table.

Example with the first part of the patch: what it looks like after selecting the original bytes, what it looks like after overwriting them with the patched code.

Save and play.

You can also reduce your mouse polling rate to 125hz. I do this via my logitech driver. 1000hz is crazy buggy, but 125 is pretty good. Its not perfect though.

Thanks so much!! that´s the solution i was looking for! Lowering polling rate helped, but this is so much better!

Thank you very much. This issue has troubled me for many years. I'm a player from China, and I noticed this problem several years ago. I asked other players in the game about it but never got a proper answer—it seems as if they didn't even notice it.

I managed to fix this for myself by typing in "/console maxfps 999" in chat, basically unlocking your framerate.

That burns your GPU, wastes electricity, and causes stuttering.

Hello, i have a problem with jumpy mouse(it resets to the middle of the screen and it also turns my camera insanely fast), ive been looking everywhere how to fix it but nothing worked, is this still an option or is it outdated?

Yes, this works fine.

If you don't have a modified exe, you can download the patched exe from the mega folder directly. No need to patch it yourself manually.

FYI, it's now 2026 and this jumping mouse cursor fix also 100% works on the HD WoTLK Overhaul, which uses a modified WoW executable. Thank you VERY much to Shred for giving us directions on how to accomplish this! Also, the link for HxD no longer works, I had to use https://hxd.en.softonic.com/

[Shred]

Glad to hear it helped you. The link works well now. It probably was a temporary issue with the website.

Hmmm, interesting note: I'm in the US and the original HxD site refuses to load for me, been trying at different times all day :P So US users might have to use the alternative site Google found for me.
