[Bug 33814] Ground Control: poor fps performance

[WineHQ Bugzilla]

https://bugs.winehq.org/show_bug.cgi?id=33814

--- Comment #28 from Steve Schnepp  ---
I'm also seeing that bug with a recent 8.0rc4 and

Vendor: Intel (0x8086)
    Device: Mesa Intel(R) HD Graphics 500 (APL 2) (0x5a85)
    Version: 20.3.5
    Accelerated: yes
    Video memory: 3072MB
    Unified memory: yes
    Preferred profile: core (0x1)
    Max core profile version: 4.6
    Max compat profile version: 4.6
    Max GLES1 profile version: 1.1
    Max GLES[23] profile version: 3.2

A perf recording showed that most of the time is spend in
wined3d_device_context_map, and indeed when I launch it with

WINEDEBUG="+fps,+timestamp,+pid,+d3d,+ddraw,+wgl,+opengl"

It seems that it is indeed many times in the same frame.

...

So the function is called many times with some adjacent boxes.
