hi all,
we are using opengl-0.3 functions for running our application and we are having multiple graphics cards in our pc.we found that only one graphics card is active in all the times.how to invoke the other graphics cards by making use of opengl functions? any opengl initialization function is there, which will initialize other cards.please help us regarding this issue.
By default, only the primary GPU is used. There are 2 ways to use multiple GPUs.
1.) You can try to enable SLI/CrossfireX in the graphics driver. The driver “emulates” a single GPU for your application, but internally renders on 2-4 GPUs. This has various downsides(Possible Problems: lag, bad scaling, readbacks being very costly, …)
