Quackshot scrolling jerky

[didier110]

Hello,

I've noticed that the scrolling of Quackshot on Genesis (the background) is jerky. I use CRT-Pi shader. even without the scrolling is not perfect. Is there a way to set something to have a smooth scrolling ?
Thanks

@didier110 the crt-pi shader isn’t known to cause frame drops like this on certain emulators/games. you can avoid it by either:

• using a different megadrive emulator (lr-picodrive may be ok?)
• editing the shader .glsl to use ‘fake gamma’. ie

//#define FAKE_GAMMA

to

#define FAKE_GAMMA

• turn the shader off ;)

Hello
Thanks for your answers. I have tried to change emulator, to disable shaders, but always the same jerky scrolling.
I use the original PI power. I've noticed that with Recalbox the scrolling is good. That is very strange.

@didier110 have you changed any settings from defaults? (eg for input lag?) what’s the file name of the rom?

No everything is from stock

@didier110 Hey, I had the same problem running Mega Bomberman.

I switched from lr-picodrive to lr-genesis-gx and all was fixed with that game. Since that, I've switched most of my sega to the lr-genesis-gx emulator.

Good luck!
