INFO: Your video card doesn't support framebuffer objects. Disabling shaders.

Framebuffer objects are OpenGL 3.0 I think. Your video cards supports up to OpenGL 2.1. No shaders for you, sorry.

but after it gets to that it just stops, does this mean I can't run this?

[NaN]

Sorry, I've missed the

not loading

part.

It fails on my intel laptop(OpenGL 2.1) too. But there are no problems to run it on a hd4850 shaders on/off. Will see if I can narrow down this issue.

Can you check the stderr.txt file? It should be in the same folder as VDrift.exe.

[NaN]

Joe, I've tracked the problem down to glGenerateMipmap(GL_TEXTURE_CUBE_MAP) in texture.cpp, line 281. It will fail with an access violation on Intel GM45.

Edit:
The loaded texture is cubereflection-nosun.png.

[joevenzon]

Interesting. I recently added mipmap generation for that texture because I was thinking about using lower mipmap levels for lower shininess reflection, although I'm not currently, so it could be changed.

Does it crash even with the latest drivers? Does that GPU not support cubemaps?

[NaN]

glGenerateMipmap(GL_TEXTURE_CUBE_MAP) is the problem. Using glGenerateMipmapEXT instead fixes it.

[trogdor87]

the stderr report is empty, I am lost with the mip map thing the only other log that has anything in it is the utility log and it says :Could not find texture: data/tex/data/cars/mustang_gt/interior.png
Could not find texture: data/cars/mustang_gt/interior.png

thats from vdrift/data/settings/logs maybe that will help
and yes I am running the latest drivers for the graphics card

trogdor87 could you try this build:

Thanks for fixing it. Why does that fix it? Driver bug?

[NaN]

Why does that fix it?

I have no idea. I think glGenerateMipmapEXT is meant to be used with FBOs. But it looks like it works for textures too( http://www.opengl.org/discussion_boards/...ber=233955 ). But then there is also: http://www.opengl.org/wiki/Common_Mistak...generation.

It would be interesting to know if it works for trogdor87.

[trogdor87]

It says I need libgcc_s_sjlj-1.dll file in order to run it once I downloaded that game started right up let me choose settings but crashed when I went to start race and the stderr is still blank

[NaN]

I need libgcc_s_sjlj-1.dll

Oops. Try this one.

well I can play practice mode but when I try single race it quits
