what is the device model and what version running now?

Looks like there is no update on the bug, maybe due to end of life device support (i am thinking).

Catalyst 2960S-24TS-L Switch

it would only peak when I would do a walk thru a number of OIDS.
When I switch to SNMPv3 it is peaking at 100% no matter which OID I read.

we found this BUG CSCty18171(SNMP poll of CISCO-PROCESS-MIB may cause high CPU and SNMP poll timeout.)
on same topic in Caveats Resolved in Cisco IOS Release 15.2(2)E7
we tried with 15.2(2)E9 as well - still same issue
CPU jumps on 100 % no matter of OID

The was more if Supervisors, but looking at your model   2960S-24TS-L - what is the outcome  if you disabled the SNMPv3 and is the CPU go to Low?

you can also check show process cpu | ex 0.00% to confirm is this due to SNMP or any other process ?

This only during MIB poling , above explained the relation between SNMP / v3
