Logitech mouse, very bad performance

As of recently, the mouse movement performance of my Logitech G9x is very bad. The sensitivity is very messed up in ScummVM.

I tried with the SetPoint installed and uninstalled. No dice.

I also tried with a no-name cheapo laser mouse I had lying around, and it's the same.

It does seem to work fine if I completely disconnect any mouse and use the touchpad instead.

Anyone else experience this?

Uhm... I took a leap of fate and downloaded the latest SDL and replaced the one installed by ScummVM, and voila! It worked wonders.

Is there any drawback to using another SDL? Is there any harm in it?

Usually, no, there shouldn't be any issues - though you'd best ask the SDL people about this

Ok, shall I post a bug report or anything?

As you said, this isn't an issue with ScummVM itself, but with SDL, so I suggest you ask them instead

Ahhh... right. My bad.

I actually found out the real issue thou, since I had the same problem in DOSBox.

It's mouse acceleration. I like to have it enabled, but both DOSBox and ScummVM dislikes it.

I'll just have to learn to not have it enabled.

The Logitech drivers have a "Game detection" screen where you can customize what happens when a game is launched. I'm not sure how games are detected, I guess they detect the usage of OpenGL or DirectX/Direct3D. But you could change mouse acceleration settings there

I hadn't thought about that.

I could even create a profile that responds only to specific programs and games.

Now I already gotten used to no acceleration, so it's all good.
