Title: PSPUAEv2 (UAE4all2-HD-Vita) Progress Update 14
Post by: FOL on 18 Oct, 2026, 10:10 AM
Been slowly adding more advanced sound, over last few days.
Gained 3 - 4 FPS, before Paula on ME work started. So just in the process of re-implementing Paula fully on ME CPU.

As I finished posting, latest compile finished.

With Paula on ME, FPS has increased by 6 - 7. So up to 46 on Bubble Bobble title screen and 39 on Game play.
This is great, havent even touched GFX yet. Still running basic.

Remember all testing is done with Skip 0 Frames. So its rendering every frame.

Just for a bit of fun, thought I would try FrameSkip=2.

Just WoW!!!!!!, feels very smooth (couldnt really tell it was frameskipping) and perfect audio.
Think switching source was perfect move. As this is working out much better on PSP @333MHz.
Audio sampling backend, still needs a bit of work, but that can wait.

Profiling shows, still another 4 - 6 fps to be had, with dumping sdl gfx and going native.

Now on to GFX backend.
