0إعدادات LAV وجنون VR المثلى لGPU نهاية عالية على 1080p

I have spent a lot of time exper­i­ment­ing with mad-vr and lav try­ing to find the optim­al set­tings for my GTX 1050Ti which out­puts to a 1080p pro­ject­or. Set­tings for high­er res­ol­u­tion dis­plays will be very dif­fer­ent, but as 4k pro­ject­ors are cur­rently so expens­ive, for a truly “home cinema” exper­i­ence 1080p is the lim­it for most people.

The first thing to do in mad­vr is to set up pro­files for dif­fer­ent res­ol­u­tion videos — 1080p videos will require far less work than much lower or high­er res­ol­u­tions, على سبيل المثال. 360ع (يحتاج الى الكثير من العمل الذي يتعين جيدا الراقي) أو 4320p (takes a lot of decod­ing). لدي أيضا 2 dif­fer­ent low-res­ol­u­tion pro­files, one of which gets filtered by file exten­sion so I can use dif­fer­ent set­tings for par­tic­u­larly low qual­ity old divx videos.

التالي, spend some time read­ing an up-to-date art­icle about all the set­tings. Many guides get out of date as the avail­able set­tings change so make sure the inform­a­tion is up-to-date.

بعض use­ful inform­a­tion on which decod­ing mode to use in LAV is avail­able. I recom­mend DXVA2 Nat­ive (لا copyback)

Fun­da­ment­ally, mad­vr is pro­cessing lots of frames per second. So it can­’t spend very long on each frame to main­tain smooth play­back. Render times over 40ms will almost cer­tainly res­ult in dropped frames. The frame rate of the con­tent will also mat­ter: 60إطارا في الثانية هو العمل أصعب بكثير من 24fps. You may want to have dif­fer­ent pro­files for dif­fer­ent frame-rate content.

25fps / 24fps40الآنسة

من حيث الأحجام, I group them as there are a lot of dif­fer­ent poten­tial sizes. Very little con­tent is in 4:3 نسبة, so in most cases the con­tent will be either 16:9 أو سوف تعرض في شكل letterboxed

SD con­tent is usu­ally 360p, 480ص أو 576P. As 360p is so rare I focus on 480p con­tent for SD as set­tings suit­able for 480p60 will cope with 576p as well. I then have cat­egor­ies for 720p, 1080ع, 2160p و 4320p.
ومع ذلك, I recom­mend using the width of the con­tent, rather than the height in pro­cessing rules. أوسع الشكل الذي من المحتمل أن تواجه هي UltraPanavision70 وهو 2.76:1. Using this aspect ratio would see 720p con­tent have an actu­al res­ol­u­tion of 1280×464. Many videos in these wider formats have had the let­ter­box­ing cut off, and the prob­lem of defin­ing sizes begins…

There are formats below 360p but you are very unlikely to have any watch­able videos in those formats.

4ك 2160P UHD1600–21602880–4096
8ك 4320p SUHD3200–43205760–8192

وبالتالي, to be com­pre­hens­ive we need rules for both width and height of the video. Any video with a height great­er than 2160 or a width great­er than 4096 will have to be regarded as great­er than 4k, لذلك سنقوم التعامل معها على أنها 8K, وما إلى ذلك وهلم جرا

2160ع10802048
1080ع7201280

وبالتالي, the fol­low­ing set of rules would do the job to group by both res­ol­u­tion and to split into 4 fram­er­ate groups (59–60fps; 47–50fps; 29–30fps; 23–25fps)

You may well wish to use a smal­ler num­ber of group­ings as it is likely you will get a lot of over­lap in set­tings with some of these set­tings. I find that I only need to split by fram­er­ate for the lower resolutions.

إذا (deintFps > 50) و ((srcWidth  4096) أو (srcHeight  2160)) "4320p60"
آخر إذا (deintFps >= 47) و ((srcWidth  4096) أو (srcHeight  2160)) "4320p50"
آخر إذا (deintFps >= 29) و ((srcWidth  4096) أو (srcHeight  2160)) "4320p30"
آخر إذا (deintFps  29) و ((srcWidth  4096) أو (srcHeight  2160)) "4320p25"

I will con­tin­ue to tinker and optim­ise my own set­tings, and whenev­er I have found improve­ments I will update them below.

My set­tings are as follows
