I have the chance to purchase a cheap 980ti as a friend is upgrading. But should I bite the bullet and get the 1080ti? I game on a projector at 1080p 60HZ so I guess the 1080ti would be wasted on that, cant see me getting a monitor anytime soon as I like the big screen.
1080ti on the Rift, is it worth buying one just for that? Or will the 980ti be as good?
If you play games like Assetto Corsa racing, there is a huge difference. I had the 980 (normal), when I got my rift, then I bought the Titan XP, which is about the same speed as the 1080 ti. With the 980 I had to turn everything down to some of the lowest settings. With a 1080 ti you can set almost everything up to the highest settings and do some super sampling as well.
With the newest games even the 1080 ti will not allow you 2.0 super sampling and everything set to max.
Is it necessary to have a 1080ti over a 980 or 980 ti? NO oculus made some good optimizations. Is there a difference in running with a 1080ti/titan XP vs 980ti? Yes there is a HELL of a difference, but ONLY in games like Assetto corsa/Dirt rally etc, that pushes the limit of what you can do.
I run super sample of 1.5-1.6 and even 2.0 in some games, so 1.5 should almost always be a safe bet with your 1080 ti. Notice also you can almost always overclock it to give 10-12% more performance if you have enough cooling.
I find that it is better to go for some super sampling than turning AA on in most cases, but it differs from game to game. It is also almost never worth it to go from say 1.6 to 1.8 if it means ASW kicks in.
You get the most out of super sampling in the beginning. Going from 1.0 to 1.1 is much more visible than 1.9 to 2.0.
It also SEEMS like, but its not something I can back up with data, but it SEEMS like there are pivots at 1.0, 1.5 and 2.0 where going from 1.4 to 1.5 gives a lot more than going to 1.5 to 1.6.
I wish we would be able to see this with a click in home instead of having to rely on the debug tool... but maybe its coming, seems like something that shouldn't be so hard for them to put in and it would be super valuable, when you have that nagging doubt - did I set my settings 5% to high, so it started ASW.
