Beware other apps that hook D3D11

[Hyru]

I'm converting my shit over from D3D9 and spent almost a day \/ trying to figure out why hooking CDXGISwapChainBase::Present was crashing randomly. Turns out EVGA Precision X launches a version of RivaTuner which by default hooks D3D11 and doesn't play nicely.

I haven't tried it, but you'll probably get the same issues with tools like dxtory and fraps.

Yeah, I've actually found this issue a lot with D3D hooks, because a lot of video card softwares and even some other overlay programs (fraps comes to mind) hook some of the same functions. If you browse around here enough, there are some posted solutions.

Simple solution:
Hook an engine function like CGxDevice::Push, remove the hook after 1 call and continue your bot logic with EventSetTimer.

You don't event have to call it from hook, just copy TLS slots from main thread to your before making call to EventSetTimer.

EventSetTimer is shit. I wrote a small timer dispatcher myself:

https://code.google.com/p/d3dshark/s...erDispatcher.h

Just hook into the mainthread loop and call DispatchTimers every frame.
Also you shouldn't copy TLS slots because EventSetTimer is probably not threadsafe.

myTimer.AddTimer(0, [=] (const Utils::STimerDispatchEvt&) {
        std::cout << "this is getting called every 300 ms..." << std::endl;
        return 300;
});

Sorry if I look stupid but :
Why don't you stay hooked on CGxDevice::Push and do you stuff inside?

It's not Endscene but it shoud be safe insn't it?

I used to hook this function but I experiences some crashes, especially when I tried to call function like CastSpell.

I didn't managed to find why, that's why I'm asking why it is not safe to execute our code into this function.
