One GPU for viewport and one for rendering in the background - lags

Hey all,

I have Geforce GTX 750 Ti installed for rendering and an old Radeon HD 2600 XT installed as a graphic card for display when rendering. The monitor is connected to Geforce, but when I start rendering I connect this monitor to Radeon so that Geforce can render in the background. To my suprise, the screen gets bit laggy. I thought that rendering on the GPU that is not connected to monitor does not affect the screen display. Is that a common issue ?

Regards

it should not be lagging, it probably is because hd2600 xt is an old card or you have some driver incompatibilities.

I run quadro and titan on geforce drivers both and all is well !

Ok, I should buy a new GPU then. Thanks for reply.
