The call filter requires a list of instructions .
This can be
from a trace: Accurate but usually limited and you already have an idea where to look
by disassembling: Is buggy and you will need to filter out the wrong ones by dealing with the exceptions and then removing them
or loading a eip list from file (requires you to have a list in the first place)_

this new one adds the option to load unwind data as eip/rip addresses. Unwind data defines function starts and ends to help with exception handling

So I just recently updated to version 7.1 today and I noticed that there are two different 64-bit executables now for launching Cheat Engine. I tried searching through the 7.1 help file but couldn't find anything that clarified what the difference is between the regular 64-bit version and the 64-bit SSE-4 / AVX2 version. Are there any added benefits and/or features that come with the latter? Or should I just continue to use the regular 64-bit version of Cheat Engine? Question

the SSE4-AVX2 version is theoretically faster if your CPU supports the AVX2 instruction set (in some fpu intensive routines)

Ah, okay. So I did a quick search and was able to find out that my laptop comes with the following instruction set extensions:

Intel® SSE4.1, Intel® SSE4.2, Intel® AVX2

I'll use the AVX2 exec from now on. Thanks for the quick reply too Dark Byte! Smile

AVX2 is supported on almost all Intel processors since Haswell (that is, 4th gen+ CPUs since Q2 2013).
Some AMDs support it, too, most notably Zens since Q1 2017.
See here.

A better question is: when does CE use these instructions?
(does it really speed up CE for you?)

Please add some ID string to be able to see version (for screenshots, videos, etc). Maybe caption: - "Cheat Engine 7.1 [AVX2]" or something...

You can see the name of the process, no?

you can always use MainForm.Caption="CE AVX"

Nope, rofl. When users start making videos and screenshots here how do you find what version in use?

save this in a .lua file in the ce autorun folder:
Code:

if enumModules(getCheatEngineProcessID())[1].PathToFile:find('cheatengine%-x86_64%-SSE4%-AVX2.exe') then
  MainForm.Caption=MainForm.Caption.." SSE4-AVX2 Version"
end


Also, in practice there is no difference between the AVX and default version. It's only important if you where to edit the assemblercode of CE itself with AA scripts
