Combat mission extreme lag/choppiness

[A Canadian Cat]

Oh I may have miss-understood. Your machine does not run either the 970 or the 1080 configurable by the program the 970 is disabled since you have the amplifier added. Do I have that right now?

Like I said I don't have any experience with this form of upgrade but I happened to be picking up a new notebook and I asked the tech about this. He said two things that might be relevant here:

1) you don't get full 1080 level performance so he wondered if the step up from the mobile 970 to the 1080 would actually give you a net benefit for an OpenGL game at all.

2) the amplifier uses CPU resources to manage data transfer to the GPU. Given how CPU intensive CM is this could actually be the problem. CM gains the most performance benefit from faster CPU speeds not faster GPUs. So, it could be that the benefit you are getting from the faster GPU is being offset by the increased strain on the CPU.

Only a couple of thoughts from someone who knows less than you...
