MAMEWorld Forums - EmuChat - Galaxian, namco set 1 - lack of fluidity in horizontal movement

Hello ! good morning

I have noticed that when the enemy ships move from side to side (especially the two in the first row, yellow, red and blue, when they are in their initial position), the movement is not fluid, you can see like "small jumps"...

In the other rows it is not noticeable as much or almost at all.

With the PC equipment I have, the movement should be fluid, I didn't expect these behaviour, to be honest.

I don't know if it's a limitation in the emulation of this game itself, but as far as I remember as a child I didn't notice this on the original machine... it was all magic... Now it has become an obsession about being able to play it properly...

I've tried a little bit of everything: Overclocking my PC's CPU and GPU (even though there should be "more than enough" powerhorses to render an emulated game from this era), applying HLSL filters, removing them, changing the rendering between the various modes (bgfx, gdi, opengl), activate or deactivate vsync, lower the native resolution of my monitor, wait to synchronize in the game's video options... I don't know how many options I've tried really..., and the movement 'little jumps' is always noticeable.

I have also tried previous versions of mame other than the current one as of today, and the same thing happens in every other version.

My Windows 11 PC specs:

AMD Ryzen 7 5800X 8-Core Processor, 32 GB DDR4 3200MHz
Sapphire Pulse AMD Radeon RX 6700 XT 12GB
BenQ G2400W 60Hz Monitor

Thank you very much in advance for reading this post, and I hope you can clarify these doubts for me.

All the best !
