Read as much as you can on autism, preferably written from autistic and neurotypical perspectives. There are things about autism that seem to be common knowledge among autistic people that NTs and science seem to be completely oblivious about. There are also things that autistic people attribute to autism but are result of usual comorbidities.
When thinking about what is normal it is common to be thrown off by what your family is like. Autism is highly heritable and it’s very likely that if you’re autistic then at least one of your parents autistic is too even if they don’t know it.
If you’re after something objectively verifiable on your own then look into joint hypermobility - if you can dislocate some of your joints at will then it’s surprisingly likely that you’re some form of neurodivergent. My mind was blown by some of the recent studies in that area. I wasn’t that angry about not being diagnosed earlier when it comes to how my mind works because I found ways to cope. I was angry because it turns out that there’s a whole slew of physical conditions that seem to be specific to autism that doctors aren’t aware of usually and will never consider because of their own misconceptions about autism.
Once you understand how autism works you’ll know. By the time I got formally diagnosed I didn’t have any doubt about it myself even though I would laugh at the idea couple of months before.
This low power mode has RAM running at half the bandwidth which will really kneecap performance but is a common way to increase efficiency in mobile devices. If it was about saving power they wouldn’t make adapting existing games this hard IMO.
