Projekt lsfg-vk pripremio je neformalnu verziju alata Lossless Scalings Frame Generation (LSFG) za Linux platformu, koriste\u0107i DXVK i grafi\u010dki API Vulkan. Kod projekta napisan je na C++ jeziku i objavljen je pod MIT licencom. Razvoj je izvr\u0161en od strane entuzijasta koji je rekonstruirao funkcionalnost vlasni\u010dkog LSFG putem obrnjenog in\u017eenjeringa Windows biblioteka. <\/p>\n
Aplikacija omogu\u0107ava skaliranje prikaza gamerskih aplikacija, predvi\u0111enih za pokretanje u zasebnom prozoru, kako bi ih prikazala u punom ekranu. Alat mo\u017ee biti potreban i za eliminaciju zamu\u0107enja prikaza prilikom skaliranja koriste\u0107i standardni grafi\u010dki sustav ili za zaobila\u017eenje ograni\u010denja igara vezanih za fiksne rezolucije ekrana. Osim toga, omogu\u0107uje pove\u0107anje glatko\u0107e prikaza i pove\u0107anje fps-a u igrama koje nisu dizajnirane za visoki FPS, dodavanjem dodatnih me\u0111uframeva stvorenih na osnovu interpolacije susjednih frameova. <\/p>\n
Za rekonstrukciju nedostaju\u0107ih detalja i skaliranje u LSFG mogu se koristiti vlastiti originalni algoritmi, ali i postoje\u0107e tehnologije temeljene na strojnom u\u010denju, kao \u0161to su AMD FidelityFX Super Resolution i NVIDIA Image Scaling. Odabir algoritma ovisi o vrsti gamerskih aplikacija. Na primjer, za moderne igre preporu\u010duje se kori\u0161tenje vlastitog LS1 algoritma ili tehnologije super uzorkovanja AMD FSR. Za starije igre s pikselnom grafikom predlo\u017eeni su algoritmi Integer Scaling i xBR, a za igre u stilu crtanih filmova i anime dostupna je Anime4K. Uz same igre, modifikacija prikaza mo\u017ee se primijeniti i na emulatorima za pokretanje retro igara i igara za konzole. <\/p>\n
Skaliranje i dodavanje frameova odvija se u stvarnom vremenu i ne zahtijeva izmjene u igrama. U verziji za Linux za dodavanje frameova i intervenciju u prikazu igre koristi se povezanost obradnika u obliku dodatnog Vulkan sloja, pomo\u0107u kojeg se vr\u0161i presretanje, izvr\u0161avanje i modifikacija postoje\u0107ih Vulkan funkcija. Za kori\u0161tenje lsfg-vk dovoljno je instalirati biblioteku liblsfg-vk.so i konfigurirati njezine parametre putem varijabli okru\u017eenja. <\/p>\n
Izvorni LSFG predstavlja skompiliranu aplikaciju za Windows temeljen na D3D11 API-ju. Da bi se funkcionalnost LSFG-a reprodukovala na Linuxu, implementacija je prevedena u prikaz koji koristi Vulkan API. Za prenos za\u0161iljiva\u010da dodan je procesor koji presre\u0107e D3D11 pozive i \u010duva za\u0161iljiva\u010de na disk, kao i parser za dinami\u010dko izvla\u010denje za\u0161iljiva\u010da iz izvr\u0161nih datoteka u PE (Portable Executable) formatu. Za prenos grafi\u010dkog cjevovoda koji upravlja izvr\u0161enjem za\u0161iljiva\u010da, komponente temeljen na D3D11 API-ju iz aplikacije su izdvojene i uz pomo\u0107 DXVK-a omogu\u0107ili su njihovu funkcionalnost na Linuxu. Nakon dobijanja radne verzije zasnovane na D3D11 i DXVK-u, pomo\u0107u debaggera RenderDoc dobiven je ta\u010dan raspored Vulkan poziva, na osnovu kojeg je pripremljena finalna verzija koja direktno koristi Vulkan API. \u041f\u0440\u043e\u0435\u043a\u0442\u043e\u043c lsfg-vk \u043f\u043e\u0434\u0433\u043e\u0442\u043e\u0432\u043b\u0435\u043d
