Anti-Aliasing drops fps more heavily than usual

Setting the anti aliasing to 2 or above causes the fps to drop. When set to 1, everything is fine at 60fps, but setting it to 2 drops it to around 50. 3 causes it to drop to about 40. 4 causes 30 fps which isn't good since it's the default value. Anything above that causes it to drop to 30 and below. Texel anti aliasing causes it to worsen. 1 anti aliasing with no texel is 60 fps, but when turned on it goes as low as 55. I have 2.70 GHz on average and 8GB RAM btw

How to reproduce:
Set the anti aliasing to anything above 1
Turn on texel anti aliasing (Optional step)

What I expected:
The fps would only drop by a few frames

What I saw:
The fps dropped by nearly double digits, and drops even more on education edition

Notes:
