Some 2D titles in Atomiswave so slow? it runs fine on my Odroid XU4

genivxcom

I'm running a 16gig ram i7-3700T on a 2TB ssd so speed/power is now an issue.
but with Atomiswave titles some titles runs like half or 1/3rd of the speed.
ex. Metal Slug 6. SamuariShowdown 6.

But other titles like Dolphin Blue runs perfectly fine.
What is wrong? it was like this in 5.24 and just updated to 5.25 and not difference. I had a retropi build on my Odroid XU4 SBC and it was able to run Metal Slug 6 fine..

Seems like Flycast has issue with Aatomiswave titles that are heavy in 2D. anyone able to figure out what is causing the slowdown on x84/x64 platform?

The same happened to me...even if I am using a "poor" Intel NUC (CPU Celeron N3050 1,6 Ghz - 4 GB ram DDR3 and Intel HD 400 graphic) therefore I presume it is not just a matter of "computing power" but emulator optimization.

Same Issue here on my NUC ... Metal Slug 6 is unplayable & Dolphin Blue runs smooth.
Intel® Core™ i5-5250U Processor
Intel® HD Graphics 6000
8GB Ram

If i use the mslug6.zip instead of the bin & lst file it runs smooth.

I see a general improvement updating batocera from 5.24 to 5.25 (especially the sound) and updating romset to MAME .218. Fist of the North Star and Dolphin Blue are very good...Samurai showdown is unplayable...Metal Slug 6 is not bad from frame rate point of view even if sound is terrible

looks like this is a romset issue? when I load the roms it complain about to use the MAME romset instead

Confirmed. I used an alternative romset downloaded from internet archive amd metal slug and samurai showdown ran fine
