Torchlight 2 on Steam hangs on mouse movement

[zlg]

I've had this interesting issue happening for a while now. I don't recall downgrading the Nvidia driver helping (currently on 361.28 for other games, I remember it working on 355 and 358).

Basically, the game runs at a choppy 30-ish frames (usual is between 50 and 60) until I move my mouse. Then it hangs until it "catches up" and continues rendering as normal... until I move my mouse cursor again.

Other games like Borderlands 2 and TPS work, Hyper Light Drifter, Unity games, etc. Even the Humble Bundle version of Torchlight 1 (through an overlay) works fine. So I'm kinda stumped as to what's going on.

Attempting to run the binary directly doesn't give me a GUI or even any terminal output (I have to Ctrl+C). However, `ldd` output:

I'm on ~arch, Gentoo x86-64, developer profile. It did this on a standard user profile on my last install too, however.

I can test this evening, I'll keep you posted.

Last time I checked ( 2 weeks ago ? ) it was working fine.

I'm running mostly stable minus the kernel ( 4.5.1 ), nvidia-drivers and a bunch of small programs in ~amd64

Hello, reporting back.

It works fine for me with kernel 4.5.1 & driver 361.28. Let me know if I can help you further or if you want some more info

Last time I played T2 it was fine. I know this doesn't help but it does imply itnfixable. Just need to find out what

Sorry for the late reply, didn't saw the response and haven't been notified of it strangely !

I get pretty much the same output if I launch the 64-bit version. I don't use that LD_LIBRARY_PATH hack, so I'll try that later today and edit this post with my results.

EDIT: I did a little more testing. When TL2 is in windowed mode, moving the cursor *outside* the window works fine and the game doesn't slow down at all. This is only affecting the game itself.

I tried loading Steam with the LD_LIBRARY_PATH hack and still had the slowdown problem. However, because I tried that in a terminal, it got TL2 to report its information to the terminal. It looks like it has issues with a few bones from the meshes but otherwise goes on. When TL2 is exited (after running Steam in this fashion), Steam crashes due to a segfault.

(my terminal didn't have enough scrollback)

So it seems to me that those warnings about the bones are probably no big deal, but nothing else in the output indicates bad juju. It'd be nice to know how Steam loads TL2 so I can emulate it and capture its stdout or something.

Ah, too bad the output isn't really helping,

Maybe try go to to do the verify integrity within steam to redownload any corrupted files ?

Are you using the Steam runtime by the way ?

Cheers !

@Myu: Yeah, I've checked the integrity multiple times and everything's good with the game files. I'm also using the Steam runtime since it'd be a (worse) dependency nightmare otherwise.

[Myu]

That's a tough nut to crack for sure !

Could it be related to the mouse acceleration ? I know Linux can be bizarre about this.

Maybe there's a settings under either your DE or T2 itself to tweak it ?

Just ran into this tonight and came across this thread. Problem seems to be the dated SDL 2 in the Steam Runtime. Emerging media-libs/libsdl2 and using LD_PRELOAD when launching Steam fixed it for me.
