Just tried it and I think it really helped. I'm always dubious of tweaks like these because I think it's mostly placebo effect, but this may have worked! Can others confirm improvement?

Edit: I even tried this in The Evil Within 2, which always had terrible framedrops and stuttering, and now my framerate is consistent. What the hell?

 

only DX12 or also DX11?

 

Whoa confirmed zero stutter fifa 19 dx12

will try a few more later

 

Lols, so that's what was holding DX12 back all along!

Makes sense though and probably works for other APIs too.
The less the OS interferes with the .exe the better performance.

Gonna try this out too in a few games.

 

If I remember it right the exe-file should be built with the support of the control flow guard and then it takes place. Also it was specially mentioned that this control flaw guard extra code should not affect the performance on modern CPUs.

Btw, I have that dumpbin.exe on my rigs so I can upload it to medifire and you can test yourself which exe-file is built with control flow guard .

So do you mean an exe must support control flow guard for it to be applied?

What if the implementation is flawed, could that explain this (why disabling it reduces stutters)?

 

Exactly.

I am not a programmer in MS kernel team. But to think logically, if exe- and dll-files were built without the CFG support the OS kernel simply has no info for CFG mitigation when it loads the exe-file.

We can assume that all system exe- and dll-files were built with CFG support (including DirectX ones). As for games we can test individually with the help of dumpbin.exe.

 

Well tried bfv with dx12 and this tweak and it was totally smooth. Is there zero way to get reshade to work with dx12 though? I cannot stand the blurry mess without it. DX11 is smooth for me, but I just feel like dx12 runs better. I could be going crazy.

 

BF V DX12 is butter-smooth even without this tweak. Try a different DX12 game.

 

A noob question for you fellow gurus: I don't have "exploit protection". Which win10 version does this relate to? 1809?

 

mbk1969 link Control Flow Guard
This feature is available in Microsoft Visual Studio 2015, and runs on "CFG-Aware" versions of Windows—the x86 and x64 releases for Desktop and Server of Windows 10 and Windows 8.1 Update (KB3000850).


Exploit protection is supported on Windows 10, version 1709 and later and Windows Server 2016, version 1803

Hope that helps

 

Yes that helps, thanks, I'm still running 1607 (LTSB 2016)

 

i try BF1 and the stutter was here nothing change to my setup and i return to dx 11 is smooth to me !!

 

Please upload dumpbin.exe, curious to see what it reports with game exes that show a benefit from this tweak (or not).

 

I will when I get to work.

I packed both x64 and x86 versions from Visual Studio 2017.

Command line to use (from the folder with the dumpbin.exe itself):

dumpbin.exe /headers <exe_or_dll_file_path> | more

- this should show first screen like this


and you can press <Ctrl>+<C> to break further output.

 

Thanks for that. I had a quick look at a bunch of games I have and none have this entry so I guess disabling it in Exploit protection is pointless?

 

It should be pointless for the binaries built without CFG support. But any user can try it himself. Who knows - may be MS team updated the mitigation to work even for the binaries without CFG support.

 

BfV.exe has no CFG in "optional headers" so it should be pointless? Like mbk1969 stated? I have also checked a bunch of games now and none of it has it, hmm..
