Forcing an app to use your graphics card

Hey all.
Just wondered if anyone knew the correct command for forcing an app to use the version of OpenGL you have on your system?
Found out i am using 1.4 version of OpenGL and Peters program uses 2.xx. And he said 3.0 very soon.

He had me try this in a command window...

Code: Select all

"C:\Program Files\Flame Painter 2 Pro\Flame Painter 2 Pro.exe" а-graphicssystem opengl1

In hopes it would force pro 2 to use my graphics card and act like the 1.7 version i have.
It didn't work though.Does anyone know of a way to do this?

Highly unlikely it would work. A different version means different functionality. He may be using v2 stuff that is not found in your v1.7. So either he is using OpenGL v2/v3 for added functionality and you have to upgrade you own support of OpenGL, or he isn't really using v2/v3 functionality and he could code his stuff for an earlier version of OpenGL.

Agree with ofnuts - the program itself may provide an option but your system as a whole won't. Assuming you're on the latest graphics card drivers already you probably just have to hope the program option is there, or ask for it!

edit: I think -graphicssystem opengl1 is a QT build option, which might work for whoever is compiling it but won't work on the final .exe

Well i have QT build environment setup for compiling but i highly doubt Peter will give me his src code to compile it. :lol

I just updated my graphics card drivers in hopes that it would work after, and it still didn't work.I assume Peter is using QT to build Flame Painter and it works for him because of this.

Peter did inform me he is using v2 and soon will be using v3.

Sounds like it's time to get a new graphics card.

Thanks folks.

You may want to run a test program to see what level of OpenGL the system sees. A great program is GLView:

This will tell you what level your system sees and much more.

I had an older graphics card and found that the latest recommended drivers did not give me what the card said it was capable of. It was an NVidia card and I had to play with drivers that were not specifically for my card until I found found that worked.
