So, I have some shitty integrity checks scanning the .text section of my game.

I want the process to break when it accesses the last address of .text. I know for sure that the instruction, which I want to place the breakpoint on, accesses it because I used "Find out what accesses this address" on it.

Now, if I set a breakpoint with the condition that the register holding the .text addresses is equal to the last addresses of .text it just won't stop.

Obviously the text section is pretty big (54,607,353‬ bytes) so my guess is that CE slows down the thread too much by checking if the condition is met on each break?

I tried to make the addresses PAGE_NOACCESS so I would get a sweet exception I could catch, but for some reason the process just stops. (Integrity checks is the only thing that ever accesses my address)

So are there any alternatives you would recommend? Or is there anything I missed?

Set a break-on-access breakpoint on the last accessed address.

Right click menu in the hex view (bottom half of memory viewer) -> Data Breakpoint -> Break on Access.

ctrl+space will sync disassembler and hexview addresses (non-focused gets changed).
