Issues with OpenGL, have spent several hours searching for answer and tried many methods.

Hello Gents and Gentets! I have been online for some time now searching for a remedy to a rather irksome problem of mine. earlier today, I could run Half Life in regular old OpenGL mode, as always. This changed when I deleted my user profile (On Windows XP) and created a new one. Now, whenever i begin Half Life i get an error message stating that "The specefied video mode is not supported. The game will now run in software mode" The computer is stubbornly adamant regarding this, and i have tried various solutions proposed to other people both on this forum and others. Some include:Placing the nvoglnt.dll file (From WINDOWS/SYSTEM32) in the gldrv folder and changing the text in the drvmap from "Default Default gldrv/3dfxgl.dll 3Dfx Mini Driver" To "Default Default gldrv/nvoglnt.dll OpenGL Driver". Setting launch options through steam to attempt to force the mode (-gl) Uninstalling drivers, rebooting in safe mode and cleaning with Driver Cleaner Pro, then reinstalling drivers from Nvidia. I have also upgraded to DX10 in attempts to rectify this issue. My Graphics card is an ancient Nvidia MX, you may all laugh at me for that :). Until earlier today, as i said, this was not a program and opengl ran fine at 1152 screen resolution. Any help will be *greatly* appreciated, Thank you all kindly for reviewing my problem.

    Have you tried to launch the game with -w 800 -h 600 for example?

    The graphic settings are saved in the registry at HKEY_CURRENT_USER\Software\Valve\Half-Life\Settings maybe these settings are damaged or gone

    you could also type: -gldrv nvoglnt.dll in the startparameters

    Have you tried reinstalling it?

    Reinstalling it did not work, nor did the -gldrv nvoglnt.dll command. What is this about the registry? please elabourate. i've never heard of it before.

    Start --> execute: type "regedit" without the ""

    go to that directory: HKEY_CURRENT_USER\Software\Valve\Half-Life\Settings
    there are the display settings with your current resolution saved

    it should be like that (that would be a resolution of 1600x1200):

    "User Token 2"=""
    "User Token 3"=""

    but these settings should be there because you reinstalled it.

    BTW do other games with opengl work?

    The "Enginedll=hw.dll line read "Enginedll=sw.dll" instead of what it should have been. after rectifying that, i updated the Nvoglnt.dll file with the newest one and tried running OpenGl on 32 bit textures with high resolution. It worked :) thank you all so much for your help, i can now enjoy my SvenCoop and Half-Life related adventures once again!

    Hope this thread helps others with the same issue!
