Projektet lsfg-vk har f\u00f6rberett en inofficiell port av verktyget Lossless Scalings Frame Generation (LSFG) f\u00f6r Linux-plattformen, som anv\u00e4nder DXVK och grafik-API:et Vulkan. Projektets kod \u00e4r skriven i C++ och sl\u00e4ppt under MIT-licensen. Utvecklingen har utf\u00f6rts av en entusiast som har \u00e5terskapat funktionaliteten hos den propriet\u00e4ra LSFG genom omv\u00e4nd ingenj\u00f6rskonst av Windows-bibliotek. <\/p>\n
Applikationen till\u00e5ter att skala utdata fr\u00e5n spelapplikationer som \u00e4r designade f\u00f6r att k\u00f6ras i ett separat f\u00f6nster, s\u00e5 att de kan visas i helsk\u00e4rmsl\u00e4ge. Verktyget kan ocks\u00e5 beh\u00f6vas f\u00f6r att bli av med suddiga utdata vid skalning med hj\u00e4lp av den inbyggda grafiksystemet eller f\u00f6r att kringg\u00e5 begr\u00e4nsningar i spel som \u00e4r knutna till fasta sk\u00e4rmuppl\u00f6sningar. Dessutom finns det m\u00f6jlighet att \u00f6ka smidigheten i utdata och h\u00f6ja bildhastigheten i spel som inte \u00e4r designade f\u00f6r h\u00f6g FPS genom att s\u00e4tta in extra mellanliggande bilder, skapade baserat p\u00e5 interpolation av n\u00e4rliggande bilder. <\/p>\n
F\u00f6r att \u00e5terskapa saknade detaljer och skalning i LSFG kan b\u00e5de egna originalalgoritmer och befintliga teknologier baserade p\u00e5 maskininl\u00e4rning, s\u00e5som AMD FidelityFX Super Resolution och NVIDIA Image Scaling, anv\u00e4ndas. Valet av algoritm beror p\u00e5 typen av spelapplikationer. Till exempel rekommenderas den egna LS1-algoritmen eller AMD FSR-tekniken f\u00f6r moderna spel. F\u00f6r gamla spel med pixlig grafik f\u00f6resl\u00e5s algoritmerna Integer Scaling och xBR, medan algoritmen Anime4K \u00e4r tillg\u00e4nglig f\u00f6r spel i stil med tecknat och anime. Modifiering av utdata kan \u00e4ven till\u00e4mpas p\u00e5 emulatorer f\u00f6r att k\u00f6ra retrospel och spel f\u00f6r konsoler. <\/p>\n
Skalning och inl\u00e4ggning av bilder utf\u00f6rs i realtid och kr\u00e4ver ingen \u00e4ndring av spelen. I Linux-versionen anv\u00e4nds en anslutning av en hanterare i form av ett extra Vulkan-lager f\u00f6r att insertera bilder och klippa in i spelets utdata, vilket utf\u00f6r en f\u00e5ngst, exekvering och modifiering av befintliga Vulkan-funktioner. F\u00f6r att anv\u00e4nda lsfg-vk r\u00e4cker det med att installera biblioteket liblsfg-vk.so och konfigurera dess parametrar via milj\u00f6variabler. <\/p>\n
Den ursprungliga LSFG \u00e4r en sammanst\u00e4lld applikation f\u00f6r Windows baserad p\u00e5 D3D11 API. F\u00f6r att \u00e5terskapa LSFG:s funktionalitet i Linux har implementationen \u00f6versatts till en representation som anv\u00e4nder Vulkan API. F\u00f6r att \u00f6verf\u00f6ra shaders har en hanterare lagts till som f\u00e5ngar D3D11-anrop och sparar shaders till disk, samt en parser f\u00f6r dynamisk extraktion av shaders fr\u00e5n k\u00f6rbara filer i PE-format (Portable Executable). F\u00f6r att \u00f6verf\u00f6ra den grafiska pipelinen som styr shaderk\u00f6rningen har komponenter baserade p\u00e5 D3D11 isolerats fr\u00e5n applikationen och deras funktionalitet i Linux har s\u00e4kerst\u00e4llts med hj\u00e4lp av DXVK. Efter att ha f\u00e5tt en fungerande version baserad p\u00e5 D3D11 och DXVK, har en detaljerad Vulkan-anrop uppst\u00e4llning erh\u00e5llits med hj\u00e4lp av RenderDoc-debuggern, vilken l\u00e5g till grund f\u00f6r den slutliga versionen som direkt anv\u00e4nder Vulkan API. \u041f\u0440\u043e\u0435\u043a\u0442\u043e\u043c lsfg-vk \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d
