60 FPS frame doubling to 120 — any good?

[Alonzo]

I have a Rift S, and before that a Rift. Both do frame interpolation mode, doubling from 40 to 80 FPS (or 45 to 90). I find this to be frankly a fairly crummy experience, especially when using a super zoom mod—the interpolation causes blue and difficulty IDing. 
 

I figure 60 doubled to 120 might be better, because the system has more frames to work with. And 72 doubled to 144 sounds good too. Anyone have experiences to compare?

With the Index when if goes from 144hz to 72hz with motion smoothing on it's pretty smooth feeling with smaller artifacts, but quickly gets bad if it drops again which still happens for me occasionally even with a powerful computer. I use motion smoothing on every title except IL-2 because just as you say it makes it more difficult to ID a small plane moving fast across your field of view. The thing is, the faster the object moves relative to the frequency will cause further separation in the artifacts; the amount of blur you perceive. 72 is bearable for comfort seated in a plane. Walking around in a FPS type game 72 can get sickening pretty quickly without interpolation.

I run 120 hz on the Index. Motion smoothing makes it a great experiance, it's my preferred refresh rate. 144 hz is a bit too far for my pc. 1080ti and 8700k. Where high refresh really shines is sim racing.

When you say "drops again" do you mean all the way to 36 fps? I guess in frame-quadrupling mode? That sounds like it would definitely suck. Kinda why I was thinking about 60 -> 120, because the 60 is easier to maintain consistently. I'd actually be fine for pretty much everything except zoomed in IDing with the Rift S 40 -> 80 mode. It's great when just flying around.

no, 144 drops to 48, frame tripling...

I run 144Hz with Motion Smoothing to 72Hz on the Pimax 5K+. I definitely see much less artifacts than with 90/45 (which is unbearable imho) but need to lower the clouds from extreme to high. Flying with 120Hz / 60hz MS is rock solid. The 170° FOV works in these settings as well. If you want to upgrade, you may want to check out the Pimax 8K+ that supports up to 110Hz. Pretty crazy picture quality and in stock. But buy locally, don't order from China, trust me ?

144 > 72 > 48. Pretty sure it tipples it as mentioned by RedRider. I would rather have a solid 80hz over 72>144 smoothed.

Oh I agree, just I am unable to maintain a solid 80hz on my Rift S as it is, with an RTX 2080 and 8086K @ 5.0ghz. Given that reality, I'm trying to understand what the various other options might do for me. Artisan supports 120hz, so 60 -> 120 could work there, or there's Index with the modes you mentioned.

There are still artifacts with Motion Smoothing, you need to consider that. IL-2's engine will never give you 90Hz or 80Hz without small dips down at times at the moment. Maybe when deferred rendering will put more into the GPU, we'll get to have that. Obviously I recommend the Pimax (Artisan) for the added awareness - you can also use PiTool to play Rift S games, or just keep your Rift S for that as well.

 

Just, if you buy a Pimax - buy it locally. Don't order from their shop or from AliExpress. The postal services have big issues at the moment, so it'll take weeks to deliver.
