What I don't fully understand in my config is that two drivers seem active, Intel and Nvidia.

You nVidia isn't enabled in your current config at all, Jochen. Your OpenGL is fully controlled by Intel's on-board video that's hidden within the CPU case and resides on the same silicon chip as your CPU. :(

You can try and fiddle with your system Device Manager settings. If you're seeing both Intel HD Graphics and NVIDIA GeForce ... video adapters there, try and disable Intel is this configuration. Probably this will wake your nVidia GPU to life.

Alternatively, if your laptop has an integral VGA video out port and also a video out port on your discrete nVidia add-on, then an external monitor should be connected to the nVidia out port. Then you'll have a dual monitor configuration where the laptop monitor will be driven by Intel, and the extra monitor, by nVidia.

I tried that, but the result was, ehm, not satisfactory. A dark screen. I had to hold the power button for five seconds and do a minimal drivers reboot 8)

Sad to hear that Jochen,

Probably the only way out would be to use an extra monitor connected directly to nVidia's VGA out if it's available. All my PC motherboards (I now have 2 nVidia GeForce/Windows and one ATi Radeon/Linux PCs) have on-board Intel HD Graphics too but my multiple monitors are connected to nVidia/ATi outputs rather than to the native VGA out by Intel. However I can connect a monitor there too and have them all working together with just one exception that, when a program runs nVidia's advanced OpenGL and its window is dragged to the Intel-owned monitor, the OpenGL canvas remains frozen until the window is dragged back over to the nVidia/ATi side(s) again. :)

Anyway, if you aren't planning any more activities to get your nVidia up and running, then I guess I'd rather leave the app as it is. I'm now a bit sorry for having posted it at all...  :-[

I had never looked into that, now I'm a bit curious: Why the hell is Intel controlling my Nvidia card? Doesn't make sense at all. The usual Windows mess 8)

What really surprises me is that so few people complain about Windows. It just sucks to click on "look for help online", knowing with certainty that it just means wasting time because that "help" never ever returns something useful :-\

P.S.: Google is my friend :)

Congrats, Jochen!!! :D

You wouldn't believe it but actually I logged in to suggest checking your Control Center settings when I spotted that snapshot of yours (not seen when not logged in).

Anyway, now you can explore 3D to the full!  8)


(And, er, should I talk to you in Russian instead? ;)  Oh no, that's Lenovo that automatically redirects me from /it/en/ to /by/ru/... :D )

Now of course I expected dramatically increased graphics performance. I checked with my Mandelbrot implementation, but it makes absolutely no difference - about 100 ms fullscreen :(

Regular GDI/GDI+ graphics is HW accelerated, whenever possible, through MS/Intel/AMD co-operation in developing the Windows OS' stock drivers. Neither nVidia nor ATi have any relation to this process.

2D and 3D acceleration is a specialized field that requires dedicated GPU design, and this is where the both brands step in leaving Intel and Co.'s general-purpose products far behind. Both of them predominantly use OpenGL as their development platform and target, and they condescend to MS' DirectX competition to OpenGL only insofar as MS is what it is and because it also has its own, though minor, game console platform in the form of xBox. Surprisingly, gaming has always been one of the major factors in the IT industry's speedy progress towards smaller geometries and faster HW.

To enjoy the benefits of HW acceleration, you should accept the rules of the game: use dedicated graphics libraries/engines/environments (OpenGL/WebGL or DirectX) and languages (GLSL or HLSL) to develop your graphics routines and entire applications, rather than rely on occasional MoveTo()/LineTo() and turtle (literally and otherwise) graphics tactics.
