| Post subject: | Problem with samples |
Hello, I have problem with samples from Horde3D_SDK_1.0.0_Beta2. The Sample_Chicago.exe needs veeery long time to start, and there's only water with about 0-1 FPS (tragedy). The second sample, Sample_Knight.exe just crashes. My PC: WinXP Pro SP2 Athlon 2.2 GHz 1024MB RAM Radeon 9550 (Omega 3.8.231) Is it normal... ? |

Perhaps this is happening because of using the Horde3D's minimum hardware.siekan wrote: there's only water with about 0-1 FPS (tragedy) Did you have tested the offical catalyst drivers instead of omega?siekan wrote: The second sample, Sample_Knight.exe just crashes. I'm not sure but perhaps your 9550 don't supports OGL 2.0 or required shaders [hardware extensions]

Is there any warning or error in the log file? |

But don't you think Horde3D should be fixed to work on my drivers as I'm using them for a quite long time and never had any single problem with Omega?

It's the log created by Sample_Chicago: http://guns.tomkhost.com/EngineLog.html Sample_Knight crashes and doesn't create log file. |

This is the problem: Code: 1.500 Shader resource 'parallax.shader.xml': Compiling shader context 'LIGHTING' 1.578 Shader resource 'parallax.shader.xml': ShaderLog: [Linking] Link successful. The GLSL vertex shader will run in software due to the GLSL fragment shader running in software. The GLSL fragment shader will run in software - available number of ALU instructions exceeded. 1.578 Shader resource 'parallax.shader.xml': Compiling shader context 'AMBIENT' 1.594 Shader resource 'parallax.shader.xml': ShaderLog: [Linking] Warning: varying pos is written to in the vertex shader but not read in the fragment shader. Link successful. The GLSL vertex shader will run in software due to the GLSL fragment shader running in software. The GLSL fragment shader will run in software - available number of texture indirections exceeded. You could just try to use the standard shader instead of the parallax shader to see if that's the only problem. If that's the case, you can try to reduce the number of iterations in the parallax mapping shader (e.g. reduce the 4 in the for loop to 2 or 1). |

I've renamed Binaries\Content\shaders\standard.shader.xml to parallax.shader.xml and it helped - the Sample_Chicago is now working acceptable. Sample_Knight is not crashing anymore, but I have only about 0.05-0.1 FPS there, even when the knight model is not visible - shouldn't framerate increase when the model is out of screen? |

Obviously, the knight sample runs in software emulation mode on your card. I suspect that the reason for this is that your card does not support floating point blending which is required for the HDR. You could try to use the standard pipeline (there is even a key to switch the pipelins, see readme). |
