Hello there, I've got a G2 and I ran it for a short time on a 1080, which is somewhat comparable to a 1070ti, and I was not too disappointed in the performance I was getting. That said, you can just scale down the resolution that you are running the headset at if you need more performance. I didn't feel like I needed to do that when I was running it on my 1080. I've got a 3080 now and to be honest I did not notice a massive performance jump. DCS is mostly held back by CPU performance and RAM from what I understand.
