[Bug 28377] New: Mouse input causes major performance loss

http://bugs.winehq.org/show_bug.cgi?id=28377

Summary: Mouse input causes major performance loss
           Product: Wine
           Version: 1.3.28
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Since I upgraded from Wine 1.3.26 to 1.3.28, I have noticed a regression in all
games I have installed on Wine - their performance is a lot lower and in some
of them graphical glitches appear.

The performance regression is clearly due to the input. For example, if I don't
move the cursor, everything works fine - the performance is what it was earlier
and there are no glitches, but as soon as I move the mouse, the performance is
lowered dramatically (to around 1 FPS in every game I tested) and in some
cases, such as running Heroes of Might and Magic III in a virtual desktop,
graphical glitches appear (a box around the cursor that displays incorrect data
- from another part of the screen).

Please run a regression test:

All right, here is the result:

commit 94ae743ea668e49d40ae4e2dc5fe1f5d9be018cb
Author: Henri Verbeet
Date:   Tue Aug 30 20:12:31 2011 +0200
    ddraw: Make the OpenGL renderer the default one.

Hmm, that explains why I got this behaviour in both HoMM3 and Star Trek: Bridge
Commander, they are both DirectDraw games. I wonder why the OpenGL renderer
fails like that, however.

Since the commit states that it just made it the default, I assume there is a
way to use a different renderer in the release build?

Also, my system specs are:
openSUSE 11.4 KDE, AMD Catalyst 11.8 (fglrx 8.88), AMD Radeon HD 4890.

Can we make this bug be about a specific application please? Preferably one
with a demo that shows the same issue. The demo for HoMM3 appears to work fine
here, is there anything specific I need to do to reproduce this?

Maybe related to bug 12689. The author can test the application in that bug and
report here.

No, this is definitely a very non-specific bug, because for me it happens on
each and every DirectDraw game I have. If you have a free directdraw
application you can suggest, I will gladly test it, since nothing comes to mind
right now.

As for that other test, I can reproduce it, but I can reproduce it on both GDI
and OpenGL without difference, and only if I press multiple buttons at the same
time, and moving the mouse does not cause any latency whatsoever. So it seems
to not be related to this issue, since for this issue I get a very low
framerate only by moving the mouse, and it works instantly, plus the framerate
goes right back to normal after I stop moving it.

I also tested a few different modes of Heroes3HD, where they have several
renderers to offer. If I choose the MMX renderer, I get a lower framerate than
with forced GDI, and no graphical glitches. With the GDI renderer, of course,
the performance is as it should be. With the auto and default renderers, I get
graphical glitches and the lowest performance.

The problem is that bugs have to be about specific issues. You can't make a
generic bug along the lines of "Some applications don't work very well with
Wine", since it would never be fixed. It's ok for a bug to affect multiple
applications, but then you have to list them, and it has to be about a specific
problem. At the moment, I simply can't reproduce this bug.

Bridge Commander's mantainer here, I tested BC with the latest wine versions
and I have seen no difference or the behaviour you're experiencing on a Nvidia
card, so might be a fglrx bug/issue.

If Henri want to test this one the BC demo is at
http://bridgecommander.filefront.com/file/Bridge_Commander_Demo;1752

But it is not uncommon that ATI cards have issues with Bridge Commander, at our
appdb page there's a:

"The game seems to have problems with ATI Radeon cards. I use the opensource
driver, and have a very slow overall appearance of the game (The same appears
with the proprietary driver). Even the mouse pointer does not move smoothly (As
if the bug above is not resolved yet for ATI cards??) Apart from being very
slow, everything works, even the videos."

And unluckily for ATI owners is an issue that from time to time resurface.

Resolving this INVALID. Please create a specific bug for a specific application
if this is still an issue.
