Every report adds a line for video memory outside VMA (the driver's usage and budget per heap against VMA's blocks, and counts of pipelines by kind and by last use, stage libraries, compute pipelines, layouts and descriptor pools, with the swapchain, DLSS and FSR sizes), a line that splits the process's commit by owner (the game's heap and maps, device-local memory, VMA's host blocks, the C runtime heap with the shader caches, pipeline tables, texture cache, log queue and flight recorder in it, the driver's pipeline cache data and the rest), and a line naming what grew by more than 64 MiB since the report before and since play began. Every ten minutes of play and at exit a ranking line orders the categories by growth and marks those that only climbed; tests/mem_growth_check.py checks that bookkeeping.

AMD's Windows driver gives the graphics family a single queue. vk_device.c then made no frame generation queues, and
vk_fg_create_swapchain returned without a log line: AMD FSR 3.1 frame generation set in the menu did nothing on an
RX 580. The present queue (which nothing else may submit to) and the image acquire queue now come from a family that
can present, compute families first, with their families passed to AMD's swapchain; the log names them, or says that
there are none, and the menu offers FSR 3.1 frame generation only where they exist.

The row showed AMD FSR 3.1 alone, and the frame generation of AMD's FSR SDK 2.4 could only be set in nx2navi.ini.
It is now listed after AMD FSR 3.1 as "AMD FSR 4 library" with the version the library runs on the card (3.1.6 on
an RX 7900 XT, the machine-learned 4.x on a Radeon RX 9000), where its libraries are there and FSR 4 runs. Choosing
it sets fsr4_fg and, since it generates only beside FSR 4 upscaling, FSR 4 as the upscaler; choosing AMD FSR 3.1
clears fsr4_fg. The performance overlay names the one whose swapchain is in place. In a test run the row went from
AMD FSR 3.1 to the new choice, back and to it again, and the swapchain followed each time.

runtime/vk_fg4.cpp makes the frame generation swapchain and context with the libraries FSR 4 comes with
(amd_fidelityfx_loader_vk.dll and amd_fidelityfx_framegeneration_vk.dll beside the executable). vk_fg.cpp takes
that path only with fsr4_fg = 1 while FSR 4 is the upscaler; the default stays the FSR 3.1 library. The loader
picks the version for the card: the machine-learned FSR Frame Generation 4 on Radeon RX 9000 cards with Windows 11,
which is untested, and 3.1.6 elsewhere. On an RX 7900 XT (driver 26.10.1) it lists frame generation 3.1.6 and the
swapchains 4.0.0, which the driver brings and the loader chooses, and 3.1.7. The swapchain in place is wanted only
while its library is the one to use, so a change of the setting or of the upscaler, or a failure of this path,
takes it down as switching frame generation off does and the next present makes it with the other library.
The preparation gives this library the camera's position and axes, which FSR Frame Generation 4 requires, and a
scene scale of one metre a unit: with the 0.01 the FSR 3.1 path uses, version 3.1.6 drew grey translucent shapes
into the sky of its frames while the camera turned (160 captures of the screen during a camera sweep; clean with 1).
Both paths now generate a frame only when the picture without the HUD is there for it: generated from the
presented picture alone, the HUD would be warped with the scene behind it. In four configurations (21:9 with either
library, a 16:9 picture in a 21:9 window, a 1080 picture without HDR) every generated frame had it, and the log
counts the frames without. On screen, of the 6,404 pixels of the HUD's item button that stayed fixed through a
camera sweep with the FSR 3.1 library, 6,162 stayed fixed with this one.
Standing in Hyrule Field at 3440x1440 with FSR 4 Quality the game draws 43.0 frames a second with this path and
42.2 with the FSR 3.1 library, each shown twice over. One run changed the present mode, HDR, fullscreen, frame
generation, FSR 4, this setting and the upscaler in turn: 216 screenshots without a bad frame, and no failure.
The SDK's frame generation headers join runtime/third_party/ffx_sdk, unmodified. tools/make_kit.py and
tools/make_launcher.py take the third library from the --ffx4 folder when it is there, and tools/make_game.py
copies it beside the game.
