The way DLSS3 and 3.5 work (though not DLSS4 it seems) is they always guess a previous frame, never a next frame. They always rely on an authentic frame and guess an intermediate frame between prior to it, because they need to know the end state and interpolate backwards from it.

4. Stay on-topic; no memes, funny videos, giveaways, reposts, or low-effort posts
This community is mostly for discussion and news. Remember to search for the thing you’re submitting before posting to see if it’s already been posted.

Don’t share it here, there are other places to find it. Discussion of piracy is fine.
We don’t want us moderators or the admins of lemmy.world to get in trouble for linking to piracy. Therefore, any link to piracy will be removed. Discussion of it is of course allowed.
Yeah, turn based CRPGs is the only time I turn that stuff on.
But there seems to be two types of frame generation:
A real frame is generated, then it guesses, then real frame is generated.
Two real frames are generated, then they “fill in the gaps” with fake frames.
For 1 it doesn’t create lag, but it may guess wrong then have to correct on the next real frame.
For 2 the fake frames are going to be correct, but a lot of latency is added.
Neither is an issue for CRPG, but can be a huge issue in shooters, fighting games, and PvE like Dark Souls.
The problem is manufactures are now counting all the fake frames in their stats while ignoring every issue that pops up from that.
The way DLSS3 and 3.5 work (though not DLSS4 it seems) is they always guess a previous frame, never a next frame. They always rely on an authentic frame and guess an intermediate frame between prior to it, because they need to know the end state and interpolate backwards from it.

I’m not sure how AMDs frame gen works, is it different?
