--- Comment #4 from sambazley@protonmail.com --- With Wine 4.5 non-staging, I still get ~25 fps. Wine 3.19 non-staging fails to start the game though.

How would I bisect with the staging patches applied?

--- Comment #9 from Sam Bazley sambazley@protonmail.com --- Created attachment 64927 --> https://bugs.winehq.org/attachment.cgi?id=64927 dwrite log with timings

I've measured how long some functions take to run with gettimeofday. dwritetextlayout_Draw often takes 1-5ms, which adds up with each string that is rendered. Here is a list of function calls that originate from dwritetextlayout_Draw, along with the time that it takes for them run in microseconds:

dwritetextlayout_Draw 3028 layout_compute_effective_runs 3012 layout_compute 3006 layout_compute_runs 2995 layout_resolve_fonts 2851 fontfallback_MapCharacters 2593 fallback_map_characters 2561

The file attached is a log with +dwrite while I was looking at the Assetto Corsa setup menu. It includes traces that show the timings for some functions. These start with "===", which is followed by a few numbers. The first number is the total time taken for that function.

Could you test if this patch makes it any better?

Thanks for looking into this. The patch certainly improves performance. In one situation, with the patch applied I get ~70fps, and without the patch I get ~45fps. However, with d19e34d8f0 reverted, I get ~110fps, but this causes the launcher to become unstable.

--- Comment #12 from Nikolay Sivov bunglehead@gmail.com --- Thank you, that's helpful. Main issue with this path is that IDWriteFont::HasCharacter() forwards to IDWriteFontFace::HasCharacter(), creating and destroying temporary fontface for every character. I'll need to take care of such decoupling first, which is required for several methods.

Reverting original commit makes all fontfaces cached, which in turn means that every ever accessed font file remains mapped. Depending on number of fonts you got installed, 32-bit application could potentially run out of memory. Is this game 32-bit?

Yes, the launcher is 32 bit and the game is 64 bit. That would explain why the launcher crashes, and the game itself does not.

Please try this one with current wine git.

It's definitely better with the patch applied, but it's still not quite as fast as with d19e34d8f0 reverted.

With only the tyre app visible: Unpatched git: 40 fps Patched git: 80 fps d19e34d8f0 reverted: 130 fps

--- Comment #16 from Nikolay Sivov bunglehead@gmail.com --- Please try with current wine. HasCharacter() no longer has a penalty of creating temporary face object, so it should be overall faster. If it's still slower than it used to be, new perf/timing report could also help.

Nice. Thanks for testing. If you don't mind sharing, how is your game distributed, is it Steam version, standalone one, or something else? (in case we'll need to retest it at some point later)

I have two installs of the game. One using steam.exe on wine that I installed a while ago. I wrote how I installed it here https://pastebin.com/tphQUgaT. This is the installation that I used to test for this bug.

I also have it installed using native Steam with Proton. For that to work, you need to run protontricks 244210 dotnet472.
