    to setup dhewm3 do I just copy over the patched pak files into the idtech directory in the sub-directory dhewm3?

    I guess so, when I included the core there was not much information about it so I guess adding the files as dhewm3 mentioned in a directory and load them with the core should be fine.

    Doom 3 Libretro core dhewm3 coming soon to Core Updater! – Libretro

    EDIT:

    just create some subfolder for each game in idtech & then load the pak file with the matching libretro core in retroarch, tested with q1, q2 & d3

    i seem to be at a bit of a loss at the moment, as far as the emulation side goes ive got zero sound. On the kodi side ive got sound and its set to alsa over hdmi or something along those lines. Is there something that i am missing to get the sound working?

    You should have a look at the linked Wiki where the steps are described how to config the RR builds

    ElBoluTony  alisson please test LibreELEC-RPi4.arm-10.0-RR-20210323-5422dc4.img.gz moonlight should still work but detect the correct render mode without forced environment flags.

    Running perfectly. No problems so far.

    EDIT: moonlight is working always in native monitor/tv resolution. Even if set lower resolution Moonlight.conf it always uses native tv resolution. I just test in a 4K TV and the result are terrible (lot tearing). Maybe a bug in moonlight.

    Well you alter/set the resolution of your gaming host/stream & not the resolution of the actual client. I guess the RPi4 struggles to render 4k properly. ElBoluTony made some similar experiences.

    Hi you all SupervisedThinking  alisson, sorry, i was out yesterday, i've made test in Doom Eternal and here are my results:

    (Of course visually i can't check the 60FPS as the KMS driver doesn't render 4K60P).

    Video Codec - Automatic (HEVC)

    720p 60FPS - It tears the Screen, probably from the 60fps to 30fps conversion.

    1080p 60FPS - It tears the Screen, probably from the 60fps to 30fps conversion.

    4K 60FPS - Lags, and it's unplayable.

    720p 30FPS - Lags a little, maybe it's 'cause i'm used to 60fps. no tearing whatsoever

    1080p 30FPS - Lags a little, maybe it's 'cause i'm used to 60fps, no tearing whatsoever

    4K 30FPS - Lags, and it's unplayable.

    -----

    Video Codec - H.264

    720p 60FPS - Lags, but no tearing, weird, ckecked again after the log dump ¿Maybe H.264 doesn't render 720p/60fps and runs at 30fps?

    1080p 60FPS - Lags and add some black frames Decoding artifacts. and later adds more lag.

    4K 60FPS - Of course it's unsupported, but tried anyways, black screen.

    720p 30FPS - Lags

    1080p 30FPS - Lags. Decoding artifacts.

    4K 30FPS - Of course it's unsupported, but tried anyways, black screen

    4K 30FPS - Lags, and it's unplayable.

    My best results with the current state is HEVC 720p/1080p 30FPS, and ignore completly the H.264 decoder if it is possible.

    The tests were run in the same order as above (sorry for the english if it's broken) : https://drive.google.com/file/d/1B6Si6k…iew?usp=sharing

    Could you outline what you mean by:

    What does convert 60fps to 30fps? Or did you run 4k@30Hz and moonlight-qt? Though I also own 2 Samsung 4k smart TVs I only test my stuff with an AVR which is connected to a 1080p TV. I guess the overall performance is not good enough at the moment to run 4k@60Hz perfectly fine.

    According to a RPi engineer the RPi4 has an own block to decode HEVC in hardware while H.264 will be decoded by MMAL. The v4l2 decoder for H.264 is not as fast as the MMAL one & needs a rewrite to achieve similar performance. So right now there is no way to decode H.264 with moonlight proper on a RPi4 with LE, maybe it would work with MMAL but LE removed all blob APIs for reasons.

    All in all people probably should get rid of the idea to use a $40 SBC for 4k@60Hz ^^ At least for now ;)

    Out of curiosity: could you force 1080p@60Hz by using this resolution in Kodi or by config.txt? Ideally there would be an additional option in moonlight to set the stream size but also the KMS mode.

    I am able to play perfectly smooth on monitors/tv with native 1080p resolutions at 30fps (depending on the game I get no problems at 60fps) or on my LG 1680x1050 monitor at 60fps (Perfection).

    But if using a 4k TV the moonlight client automatically runs in 4k and i get terrible screen tearing, I have the same report as yours in 4k "Lags, and it's unplayable."

    In summary here:

    Monitor 1680x1050 = moonlight 1680x1050 = Perfect 1050 / 1080p 60fps

    TV 1920x1080 = moonlight 1920x1080 = Perfect 1080p 30fps (some 60fps)

    4k TV = moonlight 3840 x 2160 = looott screen tearing even setting 720p 30fps

    Well I guess the RPi4 is not able to handle streams at this resolution properly? HiassofT ping ^^

    EDIT:
    you could try this:
    4K Video Playback on Raspberry Pi 4 with LibreELEC (Alpha)

    4k HEVC video decoding and output up to 30fps works fine in kodi - can't comment on moonlight as I don't use it.

    4kp60 video output and HEVC decoder optimizations to support 4kp60 are currently in the queue - no ETA for that, though.

    so long,

    Hias

    Hi! The max output supported in RPi4 is 4K@30
    Enabling 4K@60 breaks things, there are a couple of threads on this and Hias just confimed.
    So running moonlight-qt at 720p/1080p@60 and the RPi4 and TV/Monitor at 4K@30 will probably desync the vertical refresh.


    I don't get any tearing running moonlight-qt at HEVC 720p/1080p@30 in my RPi4/TV at 4K@30

    In Kodi makes no effect. will try on config.txt later.

    Hi SupervisedThinking restoring my backup did not work. Got tons of add-on errors incl. libretro and the system couldn't mount certain folders while booting. ...The games weren't playing. TVheadend however did work.

    Games are running fine on a fresh install - have tested some psx and n64 games. So it seems to rely on my config.

    Guess I should not restore all of my config.

    Have archived this post from chewitt back then - though I could make use of it someday:

    RE: Restore backup on different architecture

    Will keep on trying.

    Well backing up Kodi add-ons which have updated Kodi 19 versions probably works as tvheadend proved but backing up the .config folder & restoring it is literally the thing I tell people not to do because that's exactly the way to generate a broken build ¯\_(ツ)_/¯

    Hi! I'm scratching my head, 'cause i was unable to force a mode yet.

    Forget that, yes, i was able to force it, 1080p@60, i still feel a delay, but is smooth.
