For some reason on the toshiba laptop from 2012 the opengl driver loads very slowly. (Toshiba laptop L670 2012/Intel/AMD/RadeON)
So slow that I believed the application "frooze/hang" but this is not the cause.
1. I "hacked" the driver version number to try and make Star War Battlefront 2 run.
2. AMD installed a bad driver, or sabotaged the laptop trying to make it run slow.
3. Microsoft fucked up and installed some bad driver to make the laptop run slow.
4. The slow 5200 RPM harddisk is responsible for the slow load. Though 80 MB/sec should be enough ?!
It's suspicious at the very least.
My question is: Is there a programmatic way to tell how long it will take to load the opengl driver ? Is there a way to tell when it's done, besides from ofcourse the rendering suddenly kicking in.
I did a quick google and find two threads that might be of some interesting:
The OpenGL runtime accesses the registry to determine which OpenGL installable client driver (ICD) to load.
To load the OpenGL ICD, the OpenGL runtime:
Determines the name, version, and flags that are associated with the OpenGL ICD by calling the
D3DKMTQueryAdapterInfo function with the KMTQAITYPE_UMOPENGLINFO value set in the Type member of the
D3DKMT_QUERYADAPTERINFO structure that the pData parameter points to.
Checks the version number of the OpenGL ICD that D3DKMTQueryAdapterInfo returns to validate the version
of the OpenGL ICD.
Loads the OpenGL ICD by using the name of the OpenGL ICD.
Initializes access to the OpenGL ICD's functions. Note To obtain a license for the OpenGL ICD
Development Kit, contact the OpenGL Issues team.
To locate the name of the OpenGL ICD, D3DKMTQueryAdapterInfo searches the registry in the following key:
This key also contains the names of the Microsoft Direct3D user-mode display drivers. This key contains four
registry entries for 32-bit Windows Vista display drivers that are used on 32-bit Windows Vista and four
entries for 32-bit Windows Vista display drivers that are used on 64-bit Windows Vista. The following entries
are for 32-bit Windows Vista display drivers that are used on 32-bit Windows Vista:
The name of the Direct3D user-mode display driver, which is required for the operation of a Direct3D
rendering device regardless of whether the operating system supports an OpenGL ICD.
The name of the OpenGL ICD. For example, if the OpenGL ICD is Mydriver.dll, the value of this entry is
The version number of the OpenGL ICD that the OpenGL runtime uses to validate the version of the OpenGL ICD.
A flag bitmask. Currently, bit 0 (0x00000001) is set for compatibility. When bit 1 (0x00000002) is set, the
OpenGL runtime does not call the ICD's finish function before the runtime calls the ICD's swap-buffers
The following entries are for 32-bit Windows Vista display drivers that are used on 64-bit Windows Vista:
The name of the 32-bit Microsoft Direct3D user-mode display driver for 64-bit Windows Vista.
The name of the 32-bit OpenGL ICD for 64-bit Windows Vista.
The version number of the 32-bit OpenGL ICD for 64-bit Windows Vista.
A flag bitmask of the 32-bit OpenGL ICD for 64-bit Windows Vista.
Has anybody ever developed a "loading opengl driver" window/display ?
I could place a label behind the render window and tell the user:
"please wait for the opengl driver to load".
Bye for now,
