I think it’s fine because the recording is not saved unless you explicitly tell it to save. If it’s anything like Nvidia’s shadow play, you set an amount of time, say 5 minutes that it keeps in memory, and when you save the clip, it simply saves that file containing the last 5 minutes.
I’ve found tuxedo to be quite expensive compared to their competition, namely Slimbook. Definitely look at their website, you will likely find the same computer over there as well since they are not custom designed laptops
