Getting the best N64 experience on a Pi 4
-
@Jste84 performance is definitely better on my pi 4. Are you sure you are comparing the same emulators?
-
@quicksilver has the default emulator changed? I've only had 3 games on mario 64, f-zero and Goldeneye to be fair. will do more testing tomorrow
-
@Jste84 yes I believe the defaults have changed
-
@dankcushions so I tested with my overclock off and performance definitely went down. However the spinning Nintendo logo at the begining was fullspeed. Then I remembered that I always lower the display res in runcommand to 640x480 for the n64 emulators. Once I reset to the default 1920x1080 the Nintendo logo became very choppy. So the upscaling to 1080p is causing a big performance hit.

thanks, that was enough for me to figure it out! the issue is this setting:
EnableHybridFilter = TrueIt's a recent addition to GLideN64 that allows better upscaling (less uneven pixels), but appears to be a major performance hit. if you set this to False the performance issues go away (even at 1080p). PR incoming to fix this for future installs, but those of you running current, paste the following into a command line session:
source ~/RetroPie-Setup/scriptmodules/inifuncs.sh iniConfig ' = ' iniSet "EnableHybridFilter" "False" "/opt/retropie/configs/n64/mupen64plus.cfg"thanks again @quicksilver - you've helped so much with n64!

@dankcushions is this something that needs looked into for lr-mupen64plus-next? I know that it follows gliden64 closely but I don't see the setting exposed in the retroarch menu.

I find that Pilotwings goes to a black screen when I enter a level on anything except GLide-N64. Is this normal?
No it's not normal, I'm able to run pilot wings with gles2rice and levels load normally (gles2rice needs it's screen update settings tweaked in the mupen64plus.cfg otherwise you'll get a really strange jitter effect on screen on the pi 4. I'm using setting 7 as it seems to be the least problematic but not of the settings seem to perfectly resolve the issue). This may be another setting that needs changed for pi 4 users @dankcushions. I know you aren't a fan of the old plugins but there are still some games that just don't perform well using gliden64 or mupen64plus-next.

they will expose the option in later releases, but right now it looks like it's always enabled, unless i'm reading the code wrong.

other than some horrible slowdown in the menus, pilotwings 64 seems to perform ok for in-game for GLideN64?
-
I can play Pilotwings N64 on GLide-N64 just not any others. On gles2n64 it opens in a tiny square in the bottom of the screen and in gles2rice the screen has an odd off-putting jitter.
-
@dankcushions it may not be the best example but there are other games where the difference is more pronounced, excitebike 64, crusin USA, clayfighters etc. for example. Either way, without changing the screen update setting gles2rice is useless on the pi 4.
@George-Spiggott see my post above on how to fix the gles2rice jitter issue for the pi 4.
-
@dankcushions Unfortunately the games I’m trying to improve performance with, Cruis’n USA for example, doesn’t even work with that emulator...
It seems like we are half way there, I can run many N64 games on the Pi 4 that I couldn’t on the Pi 3 but they have issues. Either the emulators will need to improve, which probably won’t happen, or maybe a Pi 5 will run them properly
-
There are still improvements to the GPU drivers like Vulcan implementation that may have benefits for N64 (also PSP and Dreamcast) performance.

just tried it - works fine for me? some slowdown but it 'works'

For that particular game use gles2rice. You'll also need to modify the mupen64plus.cfg located at /opt/retropie/configs/n64/mupen64plus.cfg at the bottom under the video-rice section change screen update setting to 7 and it will get rid of the strange "jitter" issue that gles2rice has on the pi 4. The game is still a little slow here and there but it's certainly "playable".

@George-Spiggott Where did you edit this for mupen64plus-next? I cannot find the config file or the option to edit this setting like I could find for mupen64plus. I am only experiencing the 'line' when I use mupen64plus-next.

@dankcushions https://github.com/gonetz/GLideN64/commit/438bcc460f07ad3c9e25b8bd4e72581a443c2a7c
I'll test this out and see if it fixes our slowdown issues with the hybrid filter.
Edit: looks like youre already aware of this change, sorry for pinging you :p
-
Is there anything specific that is needed to run the standalone Mupen64plus? I've installed the latest binary and source versions from the Retropie setup but it keeps giving this error (even though this file is available at: /opt/retropie/emulators/mupen64plus/lib/mupen64plus)
UI-Console Error: Specified Video plugin not found: mupen64plus-video-GLideN64.so -
@rittnasty Hotkey + X takes you to the menu to change the settings, there is no file to edit.
@quicksilver I fixed Pilotwings, thanks.

Hey,
So whats the news about the n64 ?
any moves to make it better ? (pi4 )
