Hello.

I've started playing the original SM Galaxy and it starts stuttering at random places, usually when there is bright colours.
SMG 2 has none of these issues, ive been able to play that with almost no issues.



specs.

- Memory Size: 8GB
- Processor type: 8th Gen Intel ®Core™ i7-8550U Processor (8MB Cache, up to 4.0GHz)
- Graphics: AMD Radeon™ 520 Graphics with 2GB GDDR5

The "bright" colours probalbly have something to do with the halo effects in the game, which are done in a separate buffer on the GameCube… a buffer that doesn't exist on PC, thus instead of being able to do this in "real-time" on hardware it has to be translated to something a PC can use and then emulated in software which is a lot slower. I was wrong... see JosJuice's comment below.

On top of that your CPU is a U version which stands for Ultra low voltage/power: this means that it is made to last long on a battery not for high performance, but it should be good enough.
The one thing I can recommend for you is to try and change the video back-end to either Vulkan or Direct3D12, make sure not to use any enhancements that aren't turned on by default and run at 1x IR, then check if it still happens, if it does then your laptop is too slow to run the game without issue.
Check my profile for up to date specs.

The problem isn't that it has to be done in software or that a buffer doesn't exist, it's that extra synchronization is required between the CPU and GPU. But you are indeed right in that the visual effects involving the sun make the game run significantly slower in Dolphin.

Didn't I read in one of the reports that switching to Vulkan helped to mitigate that issue?
