somehow I managed to regain performance in FB-neo

patomax

I have a Raspberry Pi 3B + and I did the complete retropie update (4.7.1 Buster) to be able to test the pegasus frontend, the thing is that I started to notice performance problems in Neo-Geo games and others, especially those like Garou and Kabuki Klash who also had an ugly orange box covering the title.

To get the performance that I used to have, I installed lr-fb-alpha2012, but many roms didn't run, so I went back to FB-Neo to try other options.

The point is that when I retested the same game with FB-Neo, now it ran fine, with the performance it had with the previous version of lr-fbalpha, so I have absolutely no idea what could have changed but now everything works in a better way and with the improvements that fb-neo offers over some games.

I comment it to know if someone has the same problem or if it is just something that happens with my installation of RetroPie.

@patomax any idea how that happened? ever since alpha changed to neo my performance across the board has absolutely tanked on all but the most primitive arcade games.

@tobas I don't really know, I don't have the programming skills to know.
but you can try it, install lr-fb-alpha2012 and try to use it to run the game that has performance problems, regardless of whether it runs or not, rerun the same game with FB-Neo and tell me if it changes something.

so I could be sure that it was that change that improved performance and not something else.

All i can say is that it's not normal, FBNeo should be about the same speed as the latest FBAlpha builds from 2019, maybe take a look at https://github.com/libretro/FBNeo/tree/master/src/burner/libretro#game-xxx-runs-slowly-why-

Considering that and the fact it suddenly ran well again after launching another core, i have no doubt another program was corrupting FBNeo's memory. Imho, make sure RetroArch and FBNeo are up-to-date from sources, and maybe avoid that pegasus frontend if it's experimental...

@barbudreadmon hmm, the point is that it was a clean installation (even before installing Pegasus), and as I read several have a similar problem.

Could it be because the version that comes pre-installed in retropie is giving problems? In other words, would it be better to uninstall that version and install from source?

I don't think so, that's the first time i hear about that corrupted title on kabukikl ? That sounds like something that could only happen when something is corrupting the emulator.

It could be, i don't know, the RetroPie guys don't inform me of the version they pre-install. I'll always recommend current version built from source, since that's the version with the latest fixes.

I face indeed the same issue, i recently started using my Pi3B+ again to make a Sega only system, and after a clean install, FBNEO performs really poorly. compared to the FBALPHA it used to run before i stopped using that Pi.
In any event I'll try the suggestions here, and also have a look which version is included by default before i update it.
