Hi, ive replaced SDL.lib and SDLmain.lib in release mode and this is what i get with one of the code examples:

Screen BPP: 24
Vendor : Microsoft Corporation
Renderer : GDI Generic
Version : 1.1.0
Extensions : GL_WIN_swap_hint GL_EXT_bgra GL_EXT_paletted_texture
SDL_GL_RED_SIZE: requested 8, got 8
SDL_GL_GREEN_SIZE: requested 8, got 8
SDL_GL_BLUE_SIZE: requested 8, got 8
SDL_GL_DEPTH_SIZE: requested 24, got 32
SDL_GL_DOUBLEBUFFER: requested 1, got 1
SDL_GL_ACCELERATED_VISUAL: requested 1, got 1

still no hw acceleration.....

i dont know if i should ask in the nvidia forums or rather in the dell xps forums as it's more related to my computer configuration....

Do you have any other idea?

Hi slicer4ever,

I would rather prefer if u could provide me with the modified SDL library for x86 as im not very used to compile libraries with visual studio.

Hi,
thanks for the response.
ive made the changes you suggested and still doesnt get HW acceleration. Ive also modified the "bpp" bits per pixel parameter and set it to 0 and get the same result i get by default 8 bpp.

So nothing changed. You want me to try anything else?

i've attached a program i wrote to test your video settings, tell me if it still gives you an generic rendering context.

Hi slicer4ever, with your program i do get hardware acceleration!!! This program is running on my gpu.
Here is the output

VIDEO CONTEXT INFORMATION
VENDOR: NVIDIA Corporation
RENDER: GeForce GT555M/PCIe/SSE2
VERSION: 4.2.0
COLOR BITS: 32
DEPTH BITS: 24

Can you tell me what did you use to create the window?

you said that lesson 1 of the nehe tutorials does give you an hardware accelerated context.

looking at the tutorial, it seems to specify 16 BPP(doesn't specify bits per color component), and a 16 bit z-buffer.

don't know if that will help, but perhaps we should step back and see why that works, but sdl does not.

Yesterday i was playing a bit with the code that creates an accelerated rendering context changing the SUPPORT_OPENGL feature as well as the pixel format to PDF_FORMAT_GENERIC and i wasnt still getting HW ACCELERATION, i ll keep messing with it til i find a way to disable hardware acceleration.
That may be a way to investigate yes.

i've attached a program i wrote to test your video settings, tell me if it still gives you an generic rendering context.

Thanks, I ll try it as soon as i can.
