i reckon its just poorly optimised
Hi! Are you running on a Mac? M1/M2 has terrible performance right now because it's emulating x86_64. This will be fixed eventually with an official JPackage ARM release: https://bugs.openjdk.org/browse/JDK-8310589 (and if not ready in time, I'll have to find a way to build Aarch64 binaries)
I don't have an M1/M2 to test with yet but I've heard running the desktop jar directly using an Aarch64 JVM can increase performance up to 10x. Some peeps on our Discord are exploring a solution.
I'm not happy with the performance yet, there's a lot more to do in future releases, but am generally trying to avoid premature optimisation. I expect to get performance up by 1-3 orders of magnitude before EA (this is still an Alpha!). Please watch this space, performance is important to me!!
i have an i5 12500H with a 3050 mobile and 8 gb ram. The laptop is an acer nitro 5 that is like 1 year 6 months old. My laptop isnt top of the line, but its pretty good compared a lot of other pcs people would run random itch.io games on. It has a gaming score of 86.9% on userbenchmark and 60% 3d score. I never run into issues with performance in other games and am able to run rocket league for example at 200 - 300 fps while using about 60% of my gpu due to power saving settings and whatnot that i cant be bothered changing. This is the test also https://www.userbenchmark.com/UserRun/66765969
