Hi everyone, Rich here. Per the weekly update, I'm currently working on a video about the HP Omen Transcend 14 with a paltry 65W RTX 4070. I say paltry, but I've often considered gaming laptops to occupy a curious space between handhelds and consoles - and in the case of Nvidia mobile GPUs, DLSS and frame-gen can do a lot of heavy lifting.

Above is Horizon Forbidden West at the laptop's 2880x1800 resolution using DLSS performance mode on high settings - effectively on par with PlayStation 5 in terms of quality settings at least. It will run above 30fps all day but here's the thing - system level v-sync with frame-gen gets you to 60fps in gameplay and the lag is... fine? Cutscenes are somewhat more problematic but this seems to be a problem with the Nixxes port in general.

I know a lot of people use frame-gen on Cyberpunk 2077 RT Overdrive to get to 60fps on kit like the desktop RTX 4070... so are there any scenarios where frame-gen 60fps on resource-constrained kit can actually work? I'm genuinely curious about what you make of the viability based on the example above.

I've made download versions too: https://www.digitalfoundry.net/bonus-material-horizon-forbidden-west-on-a-65w-rtx-4070-mobile

Bonus Material: Horizon Forbidden West on a 65W RTX 4070 Mobile

This is captured at the 16:10 aspect ratio of the HP Omen Transcend 14 laptop at 2880x1800 resolution using DLSS performance mode on high settings... and yes, frame generation is active with v-sync forced at the system level. Question is... does the image quality hold up to your eye?

I would be curious to know what the latency implications are. I think in the PC space we can get a little caught up in a need for ultra low latency, but console players manage to enjoy games at 30 FPS with latency that is far higher than what a Nvidia GPU with reflex will get at the same framerate. I think from a visual/artifact perspective the frame gen looks good enough. If the latency is on par to a console, I can see their being a use case for this on a laptop if you are using a wired gamepad. Millions of people choose to play these games at 30 fps with that latency. I think doubling perceived smoothness even without the benefit to latency would still be a net win(assuming the base latency is reasonable).

If 30fps is fine then frame gen 30 to 60 is fine. Been saying this since day one.

Could definitely see some artefacts from the lower framegen base but it still was perfectly fine to play im sure.

There are games where it is clearly problematic, but this is not one of them.

Is it possible that just by virtue of having peripherals with less input latency as well as an engine that is somewhat in the middle between animations and responsiveness? Also the game is not the type of game that you are dying because of a 25 ms frame time to begin with

Rich, I have an MSI gaming laptop with an i7 and an RTX4070, with 64Gigs of fairly fast DDR5 ram and a 1Tb SSD. Going from a Legion with a 2060, I can say the MSI laptop does a great job with Cyberpunk ray tracing Overdrive, with DLSS + frame Gen, I get really good results at or near 60fps with most sliders at or near max. While the mobile chipset does not match its desktop counterpart (I would say it runs more closely to a 3070 desktop), but I am really pleased with its performance, especially when gaming on the built-in monitor at 1080p. When under that resolution, the laptop can maintain 60fps on most new releases while using max settings and RT, except for some areas in Alan Wake 2, and (of course) Dragon’s Dogma 2…that game is quite frustrating. Anyway, I’m a very long time subscriber, but brand new to Patreon. Yay for me!

I have a laptop with an 80W 3070 (MSI Katana GF66 w/ i7-11800H) and the various FSR3 frame gen mods have brought new life to the thing. Cyberpunk RT Overdrive is maybe an overeach but still fits nicely into the sub-60 VRR window. while the regular RT mode runs north of 100fps. I'm quite excited to see how future frame gen titles run on the thing - all without even an Ada Lovelace GPU!
