• ENGINE.md names the software device among those that step a mover's surfaces -- the step and slope toward the viewer were said of Vulkan and GL, while the software device biases them too, as its own s... (792d13da)
• ENGINE.md says which GL scene buffers are immutable -- "each is made with immutable storage (glTexStorage2D)" held for the single-sample colour buffer and the post-process image alone: a multisampled ... (d25afecd)
• ENGINE.md says what a sound keeps -- "only its length, channels, rate and loop" left out the file's bytes, read at load and decoded again for the lip-sync shapes, and the lip-sync letters (USound) (bu... (2e1ccf9f)
• NATIVES.md's vsync note covers the Wayland window -- it named X11's and Win32's presents and nothing of the engine's own Wayland window, a dev build's, which copies the frame into its buffer and commi... (51410bf5)
• NATIVES.md says which spawns a SpawnNotify is not asked about -- an actor spawned while a notification runs, DXEngine's guard against a notification spawning without end; the original's SpawnActor is ... (6c073e39)
• DEVELOPMENT.md says what empties Save/Current -- travel to another mission or a new game, as it said, and a ?restart URL too (Engine.cpp's two DeleteSaveGameFiles), while a save's load fills it with t... (fbbff9f6)
• LICENSE.md names the third-party code where it lives and the three it lacked -- ShaderCompiler, vk_mem_alloc, volk and the Vulkan headers were named by Thirdparty/ folders that are gone (they live und... (bdcda488)
• SDL's quit event closes every window -- SDL's own SIGTERM and SIGINT handlers post it where the engine's handler is not installed, the crash report window's process, and it was dispatched to no window... (681c28c6)
• SIGHUP quits as a closed window does, with SIGTERM and SIGINT -- a closed terminal's or a logout's SIGHUP, reaching the engine in the launcher's process group, killed it at any time with the inis unwr... (ffbdf063)
• The full-screen modes are the screen's size in pixels under the X11, Wayland and Win32 windows -- the backends' default answered GetScreenSize's DIPs, so on a desktop scaled 150% the list offered 1280... (64a5048e)
• The software device's frame is kept within its guard band -- a window over 8000 pixels a side had the strip past 8000 drawn by the clear, ClearZ and the flash alone; such a frame is drawn smaller and ... (5018e71d)
• The software device's reference check compares once a frame, at its present -- it compared at every DrawRecorded, the draws within a frame too, so the log's 60 frames came after 60 calls and the pixel... (fd05277f)
• D3D11's detail fade takes the view depth as SV_Position.w gives it -- GLSL's 1 / gl_FragCoord.w was transcribed as 1 / input.pos.w, under 0.003 for any depth of 1 or more, so the fade was 1 at every d... (ed888b20)
• DXL_LAUNCHER_FD is taken out of the engine's environment once its line is open -- a relaunch of the engine's own inherited the stale number, which SDL_Init may have reused, and set FD_CLOEXEC and O_NO... (239de0e7)
• netrelay.py learns the channel types from both directions' opening bunches -- c2s and s2c each learned from its own alone, so the client's unreliable calls on the actor channels the server opened coun... (3ee9bc62)

• D3D11's rectangle upload is right for every format -- RGB8 offset its source by x bytes where a texel is 3, every rect went unmasked to the unmasked cache entry alone, a padded block texture's rect la... (9605740f)
• The music source's comment states what is read of Galaxy's song start, not a TODO -- it claimed Galaxy looks for the next non-empty pattern, which galaxy-dll.md does not say (bugs.md E15a.17) (60505620)
• The mix queue is Latency deep and UseStereo off mixes mono -- the queue was four 10 ms buffers whatever Latency said, Galaxy's mix-ahead reaching the music fade's length alone, and UseStereo=False lef... (aac20a93)
• NATIVES.md says the render device's Translucency is read and changes nothing -- it is read, saved, GET and SET, and no renderer reads it (bugs.md E5a.32) (77cdf181)
• grab.py grabs the newest window of the name -- it took the first id, which with a second "Deus Ex" window (an earlier original that outlived its run) may be that one's (bugs.md E17.S4) (227583fd)
• DrugConsole's HudWindows leaves the HUD's windows shown over the drugged view, as in play -- the console hid every window but the HUD itself, so its frame held DrunkFX's one modulated draw, which the ... (f362d4ac)
• The palette loop's phase says why it changes nothing: the original's -- LT_TexturePaletteLoop adds LightPhase in whole turns, which the byte of the turn's 256ths drops, and takes them modulo 255, so t... (b60beaa7)
• The reverb's guards for a delay and a gain of 0 say why they never fire -- they are Galaxy's setup's (0x106109f0), and UpdateReverb holds both to 0.001 and over, as Galaxy's subsystem does (bugs.md E1... (7870d4f6)

• The software device's scaffold: Settings.json's "Type": "Software" opens a bitmap window (RenderAPI::Bitmap) and a device that draws on the CPU, into an 8-bit BGRA frame with a float depth buffer at t... (f8597d4)
• The software device draws the canvas and the UI -- a frame's calls recorded (each scene node and vertex copied) and drawn at Unlock: each chunk of about 128 triangles set up and binned to tiles of 64 ... (822ca1e)
• The software device draws the 3D scene, on one thread with the float reference shading -- each triangle in clip space by its scene node's transforms, clipped where a corner lies behind the node's clip... (5f9593c)
• The software device's look in full, in fixed point -- Scene.frag in 2.14 fixed point in lanes of 16 bits, a quad of 2x2 pixels at a time, through SoftwareSimd.h's SSE2, NEON or plain loops, which give... (dfc5fc6)
• The software device on every core -- a frame drawn at Unlock on every hardware thread, the game's among them (SoftwareWorkers, DXE_SW_THREADS): the chunks' set-up shared out, then the tiles, the most ... (b537abc)
• Profiling hooks: the software device's part of unlock on a line of its own -- its front end, its tiles, its present (the ramp, the scale) and the window's present, each timed on the game's thread, whi... (5865f93)
• The software device draws while the frame is recorded -- the chunks go to the workers in waves as they close, set up and drawn into every tile on a background thread's phases while the game's thread r... (1f411ca)
• Profiling hooks re-based onto the software device's waves -- its part of unlock now the wait for the wave its workers drew while the frame was recorded, then the rest's front end and tiles, its presen... (5b88dfa)
• Which device draws, as the original's -- -nohard draws with the software device, as the original's software renderer; else Settings.json's Type where it names one; else the device the game's ini names... (266ae2a)
• Mesa's CPU drivers count as no GPU, the software device being the faster -- a Vulkan device whose only device is a CPU one (lavapipe) and a GL device on llvmpipe or softpipe do not start unless CPUDri... (c7ac0a3)
• Docs: the software device offered -- DXLauncher's Software renderer, and the device that draws where no GPU device starts (README's switches); ENGINE.md's keys name DXLauncher's renderers for Type Sof... (b2e258f)
• -noddraw's window where the software device takes a GPU device's place -- the original's software renderer has no fullscreen mode without DirectDraw, so where its GameRenderDevice does not start and W... (05858bb)
• Harness: a dxe run whose GPU device does not start fails, as an original run that falls back to SoftDrv does -- the software device then draws in its place and its frames would pass for the GPU device... (adfdb92)
• Docs swept for the software device's hand-off -- README: the renderers on the CPU too, X11's Xext among the build's files (MIT-SHM), and the engine drawing on the CPU where no GPU device starts, no lo... (0ba2243)
• Docs: what differs from the original, in the present tense -- the README's features and status, DEVELOPMENT.md, ENGINE.md and NATIVES.md say what differs, not what "still" differs, and the engine is n... (65bdd6e)
• Docs: the hand-off's last sweep -- ENGINE.md's fallback window full screen but with -noddraw (05858bb's, which only NATIVES.md said); the README's device chosen by the game's ini only for SoftDrv, as ... (59dd1e4)

• README laid out for a release, with screenshots: the game on the engine -- Liberty Island, Hong Kong's Tonnochi Road and market, the intro, a conversation's choices, the MJ12 helibase, the Ocean Lab -... (7052258)
• README: the screenshots' note names no size -- the shots are 1920x1002 frames, not the 1920x1080 it said (ad3dcdd)
• Pawn: the unused UPawn::AICanSmell goes -- the native answers 0 itself, as the original's does, and the method no one called still logged Unimplemented (b6790ca)
• Edit fields as the original's XEditWindow: rows as the large text window breaks them, kept with each one's start, its characters without and with its trailing spaces and its text state; a place's row ... (fda779a)
• The level's bDropDetail and bAggressiveLOD cleared before each level tick as the original's game engine clears them, only with a client -- not a frame-rate test to come, as the code's note had it: the... (ed390b2)
• Textures: Deus Ex's formats alone, and 5.8's mod texture paths -- UT 469's formats gone from every device (the RGB10A2 uploaders, which read their own destination, the 2D-block ones, Vulkan's BC2 to B... (ff7337f)
• Vulkan: the scene pipelines' depth bias dynamic -- 33 pipelines, 37 with the lines and points, where a mover's surfaces had 32 of their own (69 at start and on each resolution or MSAA change); the bia... (6a9ee5a)
• The scene's polygons half a pixel right of and below its middle, as D3DDrv draws the original's -- Render.dll projects a polygon's corners about FX15 but a sprite's place and a corona's about FX2, and... (47474bc)
• ConvertVectorToCoordinates as the original's -- the point in front of the eye or not wherever it lands, where DXEngine answered whether it fell inside the window, so the frob highlight's box takes in ... (b79b0ac)
• The occlusion grid's pixels as the original's: a surface's by its centre, a sprite proxy's by its upper left corner -- the original's span buffer takes a surface's pixel by its lower right corner in i... (b26be5f)
• Profiling hooks re-based on today's engine -- the surface test's hook beside the decals' test VisibleFrame gained, the rest moved lines (perf.sh on's three-way merge, perf.sh save) (e846a1e)
• Fog maps only where a fog light reaches -- a fog map takes only the fog lights a line of sight from the eye to its texels can cross, their sphere against the pyramid from the eye to its corner texels ... (094736d)
• Static actors filed in the BSP once, then in turn -- a static actor does not move (its Location const to scripts, the original moving none): filed when the level sorts its actors, static first as the ... (de4bbec)
• Profiling hooks: the BSP set-up's section takes the static actors' pass -- UpdateStaticActors inside bsp-info with the dynamic actors' loop and the movers' refiling, which the three-way merge onto the... (15370cc)

• Light maps in shared pages, the opaque surfaces by zone, texture and light map -- each light map placed, when first built at its size, in a page of 1024 texels a side (LightmapAtlas, shelves), with a ... (aea5d4c)
• Profiling hooks re-based on the light maps' pages -- VisibleFrame's include beside (b3958bc)
• Light map pages: each map's border repeats its edges -- the wrap's opposite edges made a change at any edge rewrite the border on the far side, so the part sent spanned the map and its border (Battery... (4de67a5)
• Docs swept for the hand-off -- the round's figures as they stand, without the ones before: NATIVES.md's scene's pixels (the laser's fit before the half pixel, "a sprite and the canvas draw where they ... (0af3d85)
