When a fence has been missed, we can avoid locking *most* of the time
via the double-checked locking pattern. We still lock before a second
check in case the scheduler caused us to miss the fence. If the
scheduler did cause us to miss the fence, we can drop the lock prior to
executing the callback function, as a second micro-optimization.

Game engine physics/speed for Sonic CD is tied to frame rate so limit max frame rate to 60 fps. Otherwise, the game runs too quickly for high refresh rate monitors.
HDR in Control (a patch released by a developer post-launch, not
actually in the game sadly) tries to set a video mode with
DXGI_FORMAT_R16G16B16A16_FLOAT.
This seemingly works on Windows, and based on FindClosestMode etc
documentaton, this seems required to work for any format that scanout
it supported for.
It's really not like the bpp is meaningful on Windows with the
distinction of 8bit and 10bit not working in GDI modes at all.
Nor does it end up actually setting anything on Linux/Deck where
modesets are emulated.
So, treat DXGI_FORMAT_R16G16B16A16_FLOAT as 32bpp so the
FindClosestMatchingMode and EnterFullscreenMode calls succeed.
Game seems to be doing something horrible on its own, literally impossible
to make it run smoothly. This at least seems to limit excursions to ±10ms
and fix the camera flinging back and forth when running the game through
Gamescope.
This game (or nw.js) comes with a hard-coded frame rate limit that
behaves more like a random number generator which happens to average
out at around 16ms on a good day.
Fix this complete mess by enabling ours on top of that.
This reverts commit 79f6239df3.
Some engines use SEQUENTIAL presentation despite not making use of it, and
sparse binding is much slower than expected on Nvidia drivers, which leads
to massive performance regressions across the board.
For two reasons:
1) Some apps will only enable or attempt to enable HDR if BitsPerColor is >= 10.
2) Encouraging apps to create 10-bit swapchains for use in hardware dithering on Gamescope/Steam Deck and to have more precision thru scanout color transforms
This way, memory regions bound to consecutive pages are more likely
to end up in consecutive memory regions, which allows batching page
table updates more efficiently.
Player movement and animation can bug out at high fps like issues moving around objects and the players head detaching slightly when moving backwards.
Seems like it also helps some crash issues.
NVAPI is disabled now due to crashing issues in a wine-specific code
path within the game, but we still want it to detect the correct GPU
so that it doesn't complain about drivers and also allows users to
enable Raytracing.
Disable stdcall aliasing and enable kill-at to ensure our exported
functions don't have the @8, @40, etc suffixes.
This still keeps `--enable-stdcall-fixup` as otherwise the linker can
get confused trying to find exports from the .def. This does not result
in aliases being added, just for them to be found to add to the export
table.
This also switches d3d11 to use the MinGW provided dxgi.lib for linking
and d3d10 to use the MinGW provided d3d11.lib for linking.
Unfortunately the .a's we output seem to still have the @blah that we
killed so we cannot use them for internal linkage since using kill-at.
Tested that what we get out of MinGW now is what we want with dllexp.
