Some games feel stuttery (FBAlpha)?
-
@psyke83 I never heard of video_max_swapchain_images, and I have not modified anything there. I can check to see what the value is but I am not sure where to access this. Funny you mention later 16bit games because I believe threaded video is enabled on Genesis/SNES cores and does not cause an issue. I played Sonic and Contra III to confirm stutter on my other cores and saw nothing like FBAlpha. I have to confirm again later when I am home from work.
-
@dankcushions would you like any of my files to take a look at and see if anything is out of wack?
-
@greenhawk84 sure! what directory are your roms in? that will determine which .cfg file is at play. also we would need to see the /opt/retropie/configs/all/retroarch.cfg
do you have any per-game or per-core overrides set?
-
@dankcushions - I use the Arcade, Neo-Geo, Megadrive (Genesis), SNES, and NES folders (I think that's all of them)
-
@psyke83 - as of now none of my cores use threaded_video only vsync. I tested Megadrive, NES, and SNES today and the games are very smooth.
-
You could potentially have configuration in the system-specific retroarch.cfg that would override what's in the shared configuration. The simplest way to check is to open a game using the FBAlpha core, then check the video settings menu. It's listed as
Max swapchain imagesthere, and needs to be set to 3. -
@greenhawk84
did you manage to save ''threaded video=off'? Mine is always turned on again after I restart a game. I tried saving the options on game. It's the only option I believe that isn't saved. -
@greenhawk84 @coldnpale you should probably edit the configuration files directly. To be honest i wouldn't be surprised if your version of retroarch was suffering from the same issue lr-fbalpha suffered with hiscores (not saving properly), since the buggy cross-platform file handling library that was used in lr-fbalpha was first used in retroarch.

Would updating retroarch be helpful? I have the version that came with retropie 4.3. Also, is lr-fbalpha still suffering with a buggy hiscores or is this fixed now? -

thanks! right ok, so we need to see:
/opt/retropie/configs/all/retroarch.cfg
/opt/retropie/configs/arcade/retroarch.cfg
/opt/retropie/configs/neogeo/retroarch.cfg
/opt/retropie/configs/megadrive/retroarch.cfg
/opt/retropie/configs/snes/retroarch.cfg
/opt/retropie/configs/nes/retroarch.cfg -

@coldnpale yes I was able to save my .cfg to threaded video "false." Remember there are multiple .cfgs that we have to worry about. I still need to get home later and upload them for viewing.

so that all looks fine for fba to me - i only checked fba but /all/retroarch.cfg looks fine, and so does /fba/retroarch.cfg other than video_threaded = "false" (i have nothing set, which means it's "true" as per /all/.cfg). not sure if we've proved that's not your issue or not but anyway:
so unless there's some core/game overrides going on, the only other place i can think is the /all/retroarch-core-options.cfg file. can we see that please?
-
@dankcushions - I added it to the folder. Let me know if there are any other files.
-
I'm still a bit scared to run "update installed packages" since it kept giving me the older version of FBAlpha. Anyone else run into this? I updated the setup script manually too.

this file still has the CPU overclock that i thought caused problems above
fba-cpu-speed-adjust = "170" -
@dankcushions, yes, I use this setting for the slow performance in Metal Slug games. I think someone told me at the time that dialing the overclock up would not harm anything else. I really don't notice any performance difference and the stuttering was still there when I turned it back to 100. Only when I disabled threaded video I saw FBA smooth right out back to normal.
-
I eliminated some very mild (only audible) stutter on Genesis Plus GX by setting on threaded video. It also slightly improved some titles in Nestopia and maybe FBA though it could be a placebo effect since everything runs fine in both true and false.
I previously read that it could cause some input lag but I tried out Battletoads (NES) on a CRT TV via composite with wired controllers and I played fine so I don't think it's the case at all.
-
@matchaman threaded video is on by default in retropie.
