In my experience, upgrading to 22.10 might not fix driver issues (rather it might cause some). You could try installing xanmod kernel, I found it is a lesser sacrifice that fixes my bugs and perhaps in your case, performance. Since xanmod on a uncongested Desktop runs on 1gb of ram at almost 0% CPU, in my case, not replicable with default Ubuntu fresh installs.
You can also boost performance with cpufreq or other CPU governor tinkering: just ramp up the clock...
Though if I were you, I'd take into account heat generation, since it might just end up causing your CPUs to thermal throttle or/and other damages on low quality plastic or the CPU itself (circumstantial stuff, depends on the quality of your casing/laptop and cooling capacity.
If your laptop usually overheats, do not casually boost your clock speed (I don't know whether you have that option available)
