Hi guys,

Figured we're getting enough separate threads on this; we're currently aware of the issue whereby geometry instancing crashes the SDK using the D3D11 renderer on AMD cards. Original thread is here.

Workaround
Enter r_GeomInstancing = 0 into your system.cfg to prevent these crashes, or r_Driver = DX9 to revert to the D3D9 renderer.

Your system.cfg is found in the root folder of the SDK. At present we're working on the issue. If you have any useful information to add, please do so here

Cheers,
Ruan

want work for me

it will say DLL:Cryinput.dll error is it a pacific way i must input the code

As stated in the other topic, it hangs when trying to lock a vertexbuffer from a rendermesh.

Is this a drivers issue?

System specifications,

Readeon HD 6990

Enter r_GeomInstancing = 0 into your system.cfg.

This work for me. I dont know what it is but i didnt set my directx to dx9.

Just an update on this, we're still investigating this issue but it appears as though Geometry Instancing + Tessellated objects isn't currently supported which is why disabling GeomInstancing fixes the issue. The reason AMD drivers are crashing and NVIDIA cards aren't is simply one driver falls on the issue and one doesn't. Will keep you posted on advancements but the official fix is as per the OP, to disable r_GeomInstancing. Thanks!

Hi Adam, Just to give some info as a AMD user. I disabled Geom instancing but imported one of my test Floating mountains models with Displacement and it worked, turned on wireframe and was def doing distance based tesselation. Just thought i should let you know.

Cheers! Ya, Tessellation works on both AMD and NVIDIA, Tessellation + GeomInstancing doesn't work on either. AMD drivers don't like the latter.

I don't have either of these r_GeomInstancing or r_Driver in my System.cfg file when I open it in notepad. What's wrong? The only text I have in System.cfg is this:

-- *************************************************************************************************
-- Default system.cfg configuration for development
--
-- Your personal settings can be stored in 'systemcfgoverride.cfg' so that they don't create
-- any conflicts for version control
-- *************************************************************************************************

-- Disable fullscreen mode
r_Fullscreen = 0

-- Shaders are compiled in parallel in precache mode
r_ShadersAsyncCompiling = 3

-- Disables Remote Shader Compilation
r_ShadersRemoteCompiler = 0

-- Store the shader cache in local Game directory instead of User folder (MyDocuments\MyGames)
r_ShadersUserFolder = 1

-- Defaults System Spec to High (Launcher)
sys_spec = 3

-- Disables Geometery Highlighting in SandBox
ed_highlightGeometry = 0

-- Sets Current Game Folder
sys_game_folder = Game
sys_dll_game = CryGame

sys_float_exceptions = 0

-- for development, disable loading of IMG files, load the cafs instead
-- if no IMG files were created, this will also disable the warning spam messages
ca_UseIMG_AIM = 0
ca_UseIMG_CAF = 0

-- For development only, on pc and when no dbas used, disabling unloading of on demand animations
ca_UnloadAnimationCAF = 0

r_stereodevice = 1

-- Allow Backround Generation of Navigation Mesh in Editor only
ai_MNMEditorBackgroundUpdate = 1

R_HDRBlueShift = 0

you need to add it in yourself

Just add it to the bottom somthing like the following

-- AMD fix
r_GeomInstancing = 0


Then save the file..

Thanks mate that did the trick.

Maybe it's fault on driver side then ?
Nah I think you contacted AMD on this issue, but I think it's worth mention anyway (;.

Hi, just downloaded the Free v3.4 SDK yesterday. But the Editor and Launchers (both 32-bit and 64-bit) crash on startup. Already applied the workaround mentioned above but it still doesn't resolve the problem.

Thanks in advance for any help rendered...

OMG!!!

Thank you so much for this fix!!! I kept getting AMD Display Driver crashes, and I honestly thought it was a problem with my card. I was literally about to leave to return the card when I stumbled upon this!

You are a lifesaver, thanks!!


And, as an added bonus, my frames per second increased by 15 after I did this for some reason...
