Bug ID: 45761 Summary: High CPU usage in some games Product: Wine Version: 3.14 Hardware: x86 OS: Linux Status: UNCONFIRMED Severity: normal Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: SolisX007@yahoo.com Distribution: ---
Hello everyone,
I'm getting high cpu usage in some games. For exsample
Need For Speed Hot Pursuit 2 i usually get around 58% cpu usage but with wine-3.14 i got around 70% + cpu usage.

--- Comment #3 from Henri Verbeet hverbeet@gmail.com --- Well, it's expected that enabling csmt will increase CPU utilisation. You might even say desired. Perhaps there's room for improvement, but I wouldn't consider that a regression.

--- Comment #4 from Lunknown SolisX007@yahoo.com --- Hello Henri Verbeet,
Well there should at least be a way to turn csmt off. I did not see any way to turn it of in winecfg.
BTW: On Need For Speed Hot Pursuit 2 i usually see the cpu uage to be 57%. With cmst enabled i see the cpu usage does to 100%.

--- Comment #6 from Lunknown SolisX007@yahoo.com --- Also i would like to add that i tried adding this to the registry
HKCU/Software/Wine/Direct3D/CSMT=disabled
but i still get high cpu usage.

This intentional behavior has become apparent to me as well over the past two weeks, but I don’t think it is obvious to regular users that one CPU core may constantly spin loop if their GPU is slow (e.g. waiting on present or space in the queue).

Also using more of the cpu means more heat. I like to keep my system as cool as possible.

The "csmt" registry key is a DWORD value, not a string. Set it to 0 (DWORD) to disable CSMT. See also https://wiki.winehq.org/Useful_Registry_Keys.

We've been working on optimising resource maps, but it's tricky to get right. Once those land though, we should also be able to reduce spin counts as well, since the CS thread stalling should become much rarer under normal circumstances. Likewise, it may become more reasonable to wait on an event in e.g. wined3d_cs_emit_present() at that point.
Ultimately though, that's going to help applications that don't spend all that much time rendering. CPU usage is still expected to be higher than without CSMT on average, simply because we're expected to be pushing more work to the GPU.

Ok i see. One more thing with the csmt i just notice. On Grandia 2 if i disable csmt the GameArts Video logo does not show up. Here is a video with csmt disabled.
However if i have csmt enabled the GameArts Video logo shows up. Here is a video with csmt enable on grandia 2.
So is this another bug?

--- Comment #11 from Lunknown SolisX007@yahoo.com --- Sorry i copied the video links in the wrong order.
csmt disable Grandia 2 gamearts does not show up.
csmt enable Grandia 2 gamearts does show up.
But anyways is this a csmt bug?

--- Comment #12 from Henri Verbeet hverbeet@gmail.com --- In principle, but not one that we're likely to give a high priority. Some classes of bugs are unfortunately not fixable in a reasonable way without csmt, and it's quite possible that this one belongs to one of those.
