Made some progress: Setting MouseWarpOverride = disable fixes the stutter in
TESV: Oblivion with both wined3d and Gallium Nine. Accordingly, there are also
no more frametime spikes reported in the Mesa overlay graph when moving the
mouse.

But the Hitman 2 issue seems to be different: The mouse cursor just skips a
lot, but doesn't affect rendering performance. This can already be seen in the
game's menu when moving the cursor, it partially refuses to move and can jump
back.
Disabling cursor lock for fullscreen fixes the mouse skipping in the menu, but
it makes the camera not freely movable while in game. MouseWarpOverride =
disable doesn't help here, and MouseWarpOverride = force locks the cursor in
the middle of the screen. Wine's virtual desktop doesn't help.

Still there is the connection to xf86-video-amdgpu + amdgpu.dc=1, as both
issues don't exist without that combination.
