One of two commits severely impacts performance on recent builds

[rhester72]

Somewhere between 28-Mar-2022 and 7-Apr-2022, a commit SEVERELY impaired performance (even on an overclocked RPi 4) and more than doubled the binary size.

I suspect commit https://github.com/libretro/libretro-uae/commit/022c82b63ccb0d76a35803e52fa3458542f7ebf0 due to the apparent addition of esp.c but that is a guess on my part. Something definitely significantly changed, and from what I can tell nothing in the Retropie toolchain was updated in between.

Probably due to the fact that sonninos updated PUAE to v4.5.1 for more accuracy from WinUAE. The old build is now called puae2021.

[sonninnos]

Yes, the new 4.5.0 version is to blame. The old version is kept in 2.6.1 branch for the low-power machines. Accuracy comes at a cost. No way around it I'm afraid.

[rhester72]

Understood, will ask the Retropie folks whether they can maintain both. Thank you!

You killing my dune. Now glitches with normal speed or normal graphics with glitches in audio on RPi4:(

[sonninnos]

It is what it is. Use the old core version.

[ZzackKbin]

how? retropie see only newest.

[sonninnos]

If puae2021 core is not yet available to download, you must build the 2.6.1 branch manually.

[ZzackKbin]

Is too much for me.

@ZzackKbin I've raised the question of tracking puae2021 as a separate package in RetroPie here:

https://retropie.org.uk/forum/topic/32502/can-retropie-please-track-legacy-lr-puae-now

For the time being, I'm attaching a build of 2.6.1 HEAD here, just replace your existing library with this and you'll be up to date (thus far).

puae_libretro.zip

(Unzip, copy to your RetroPie box, ssh in and copy it to /opt/retropie/libretrocores/lr-puae)

Thx :)

Enabling "Immediate Blitter" seems to also fix the graphic glitches without Cycle-exact.
