Bandicam having trouble holding hooks in DirectX 11 game(s)

Fri Mar 02, 2018 5:46 pm

Ever since the update that introduced this new user interface design, Bandicam has lost the ability to maintain its hooks in DirectX 11 game(s). I've mainly noticed this with Final Fantasy XIV's DirectX 11 client, although I wouldn't be surprised if it also happens with others.

For clarification, I know with reasonable certainty it's a DirectX 11 issue specifically, due to Bandicam having no problems whatsoever with Final Fantasy XIV's DirectX 9 client.

This is also occurring with Fortnite (both Battle Royale and Save the World) when it's running in DirectX 11 mode. This essentially confirms that Bandicam's DirectX 11 compatibility has been broken.

Hello Hexerin,

Sorry for the late response.

We have tested Fortnite and Final Fantasy XIV's DirectX 11 hooking and we were not able to recreate your issue while recording these games.

First, uninstall the graphics driver completely and install the latest version of it.

If it doesn't seem to help, please let us know your PC specs such as CPU, GPU, OS, and graphics driver version.

Thank you.

No worries!

In both cases, how did you go about testing? I see I failed to be clear when describing the issue I'm having, so any confusion is my bad.

The hooks don't fail immediately on game launch (usually, sometimes they do if Bandicam has been running for several hours but it isn't consistent). They do fail, and consistently, after the game's been running for a few hours and/or many ALT+Tab's have been performed (or possibly if leaving the game open in the background without returning for extended period).

You'd never notice in a normal development environment, where you don't really have the time to QA for stuff like this.

Hello Hexerin,

We have tested Fortnite and Final Fantasy XIV again for more than one hour hitting Alt+Tab many times and also running the games in background as you said, but unfortunately we were not able to recreate your issue again.
Please make sure that there are no problems with old versions.

We would appreciate it if you could specify the version with which the issue started to occur.

Thank you.

Currently running 4.1.2.1385, issues were introduced/started in the version prior to this. A fresh/clean install of the Bandicam software didn't fix the issue.

Hello Hexerin,

Thank you for your reply.
For further investigation, please let us know if you don't have the issue with Bandicam 4.0.2.1352.

Thank you.

You aren't alone with this. I have issue with Path of Exile in DX11 mode. I have not tested if other DX modes have the problem but I can confirm for at least one DX11 game. For me its is hard to reproduce but it usually happens after waking the PC from sleep. Sometimes I'll play the game for some time and exit. Once I come back Bandicam fails to hook the game again requiring a restart of Bandicam in some form (ie: pc restart - Bandicam is set to run on startup, or restarting the program manually).

My rig is:
i7-4790k
16GB DDR3 2800
Trion 150 480gb (Bandicam is installed here) - Bandicam records to D:\ not sure what the model of this HDD is.
Asus Z97-E
GTX 1070 8GB
Windows 10 x64 Home

Sorry guys, i know I come here with the weirdest issues but please know I only do so because I love Bandicam!

ed: it also does it with Elite Dangerous DX11 client.

OK. I will test some older versions and get back to you. Thanks for your continued support.

Alright after some testing. Just doing my normal routine, playing games, recording a bit. Version 4.0.2.1352 and newer has this issue with failing to hook DX11 games.

From the old versions, 3.4.1.1256 works flawlessly with hooking.

To be sure, I reinstalled 4.0.2.1352 and the issue returns.

ed: I got 3.4.1.1256 to stop hooking as well. It won't hook anything at all now. Let me go back a few more versions then.

ed2: Bandicam version 2.4.1.902 is blocked by Chrome for being 'dangerous'. The earliest version it lets me download is 3.0.1.1003. Is version 2.4.1.902 and below signed? Not sure what that is about.

ed3: Version 3.0.1.1003 has stopped hooking as well. I checked out the 2.x versions of Bandicam on that site and the signature is invalid or the file is corrupt. So 3.0.1.1003 is the oldest I can test and it exhibits the same behavior as the 4.x versions.

Is there any thing useful I can do to help pin down what causes this?

Well i tried reinstalling windows with a fresh user account and it is still practically unusable without restarting Bandicam multiple times to make it hook after the first game.

No idea what to do at this point.

I have a similar, possibly related issue with Bandicam on Windows 10 with DirectX 11. After Bandicam has been running for an extended time, generally 24+ hours, it will sometimes lose the ability to hook a game when it is launched. In my case mostly Kerbal Space Program, but also other games. The FPS counter does not show up in game. I have tried relaunching the game, but that doesn't work. Only exiting bandicam and restarting it works. I cant be sure (without reviewing the code), btu this appears to be an issue with a thread leaking some resource or another, and then the thread crashing when it can no longer allocate that resource, most likely a HANDLE. Then the watchdog thread, or lack thereof, does not check that the thread in question is still operating properly.

Hello Sinxar,

Thank you for your reply and sorry for the late response.
We've tested Path of Exile in DirectX11 but we had no problem with hooking the game.

From the old versions, 3.4.1.1256 works flawlessly with hooking.

So, do you mean that Bandicam 3.4.1.1256 is the only version you were able to record the game?

We are sorry to bother you, but please let us know if the problem also exists on the latest version of Bandicam which we released yesterday.

No actually. If you look at my post. none are them are working properly, at least down to the versions that I can download. I did a full fresh install of Windows 10 x64 Home (with ISO, so deleted old partitions and remade etc, not just the built in reinstall option) updated fully, got latest nvidia driver (i do not use geforce experience, i always uncheck that)... and it still happens. This is an absolute fresh install with just steam, bandicam and path of exile.

See the thing is, it works the first time trying to record, maybe even the second time the game is launched. After a while when you launch the game again, Bandicam simply refuses to hook it. I can switch to windowed and it still says to click the recording target.

I tried the latest version on the fresh install and no it suffers from the same issue. It may be relevent to note that this started back when the last "Fall Creators Update" was released for Windows 10. I suspect it is some interaction there but what exactly, i dont know.

So what you do to reproduce is to open the game in question (make sure to have fps overlay turned on) and you know play for a bit and exit the game. Wait maybe 30 minutes and open the game again and see if it is hooking. If so, exit and try again. It will stop eventually and I cannot imagine this isn't reproducible. I mean im not changing anything in windows settings or bandicam other than setting the record and overlay key (which is "/" on the numpad for record and "-" on the numpad for overlay toggle)
