Proiectul lsfg-vk a preg\u0103tit un port neoficial al utilit\u0103\u021bii Lossless Scalings Frame Generation (LSFG) pentru platforma Linux, utiliz\u00e2nd DXVK \u0219i API-ul grafic Vulkan. Codul proiectului este scris \u00een C++ \u0219i este distribuit sub licen\u021ba MIT. Dezvoltarea a fost realizat\u0103 de un entuziast extern, care a recreat func\u021bionalitatea proprietar\u0103 a LSFG prin inginerie invers\u0103 a bibliotecilor Windows. <\/p>\n
Aplica\u021bia permite scalarea ie\u0219irii aplica\u021biilor de jocuri, concepute pentru a rula \u00eentr-o fereastr\u0103 separat\u0103, pentru a le afisa \u00een modul ecran complet. De asemenea, utilitatea poate fi necesar\u0103 pentru a elimina ie\u0219irea neclar\u0103 atunci c\u00e2nd se scalare utiliz\u00e2nd subsistemul grafic standard sau pentru a ocoli limit\u0103rile jocurilor care se bazeaz\u0103 pe rezolu\u021bii fixe ale ecranului. \u00cen plus, exist\u0103 posibilitatea de a \u00eembun\u0103t\u0103\u021bi fluiditatea ie\u0219irii \u0219i de a cre\u0219te rata de cadre \u00een jocurile care nu sunt concepute pentru FPS ridicate, prin interpolarea cadrelor suplimentare create pe baza cadrelor adiacente. <\/p>\n
Pentru a recrea detaliile lips\u0103 \u0219i scalarea \u00een LSFG pot fi utilizate at\u00e2t algoritmi originali proprii, c\u00e2t \u0219i tehnologiile existente bazate pe \u00eenv\u0103\u021barea automat\u0103, cum ar fi AMD FidelityFX Super Resolution \u0219i NVIDIA Image Scaling. Alegerea algoritmului depinde de tipul aplica\u021biei de jocuri. De exemplu, pentru jocurile moderne se recomand\u0103 utilizarea algoritmului propriu LS1 sau a tehnologiei de supersampling AMD FSR. Pentru jocurile vechi cu grafic\u0103 pixelat\u0103 sunt propuse algoritmii Integer Scaling \u0219i xBR, iar pentru jocurile \u00een stil cartoon \u0219i anime este disponibil algoritmul Anime4K. Pe l\u00e2ng\u0103 jocuri, modificarea ie\u0219irii poate fi aplicat\u0103 \u0219i emulatorilor pentru a rula jocuri retro \u0219i jocuri pentru console. <\/p>\n
Scalarea \u0219i interpolarea cadrelor se realizeaz\u0103 \u00een timp real \u0219i nu necesit\u0103 modific\u0103ri \u00een jocuri. \u00cen varianta pentru Linux, pentru interpolarea cadrelor \u0219i interven\u021bia \u00een ie\u0219irea jocului se utilizeaz\u0103 un handler conectat sub form\u0103 de un strat suplimentar Vulkan, prin care se face interceptarea, executarea \u0219i modificarea func\u021biilor existente Vulkan. Pentru a utiliza lsfg-vk, este suficient s\u0103 instala\u021bi biblioteca liblsfg-vk.so \u0219i s\u0103 configura\u021bi parametrii acesteia prin variabile de mediu. <\/p>\n
LSFG original reprezint\u0103 o aplica\u021bie compilat\u0103 pentru Windows bazat\u0103 pe API D3D11. Pentru a recrea func\u021bionalitatea LSFG pe Linux, implementarea a fost transformat\u0103 \u00eentr-o reprezentare care folose\u0219te API Vulkan. Pentru transferul shaderelor, a fost ad\u0103ugat un handler care intercepta apelurile D3D11 \u0219i salva shader-ele pe disc, precum \u0219i un parser pentru extragerea dinamic\u0103 a shaderelor din fi\u0219ierele executabile \u00een format PE (Portable Executable). Pentru a transfera conduita grafic\u0103 care controleaz\u0103 execu\u021bia shaderelor, componentele bazate pe API D3D11 au fost extrase din aplica\u021bie \u0219i prin intermediul DXVK s-a asigurat func\u021bionarea lor pe Linux. Dup\u0103 ob\u021binerea unei versiuni func\u021bionale bazate pe D3D11 \u0219i DXVK, a fost utilizat debuggerul RenderDoc pentru a ob\u021bine o trasare exact\u0103 a apelurilor Vulkan, pe baza c\u0103reia a fost preg\u0103tit\u0103 versiunea final\u0103, care folose\u0219te direct API Vulkan. \u041f\u0440\u043e\u0435\u043a\u0442\u043e\u043c lsfg-vk
