Thanks, that's forced it on to the GTX. Meant to do that ages ago but long forgot to. However it's now running a solid 4FPS in the menu......

Also, from GeForce Experience, at the optimisation screen, in now says "Unable to retrieve all current settings. Try restarting the game or changing the settings within the game first."

Thanks for the reply, checked and both the global setting and program-specific settings are the primary GPU.

Thanks for getting back to me, and sorry for the late reply; no notifications came through, I'll check my settings. Would you prefer it posted here or as a message as mentioned in the forum thread?

Also, is there any access code to go back to playing 1.44?

Thanks for your quick reply, Adam.

All OS / driver software is up to date. I've already tried verifying the game cache integrity and multiple reinstalls.
