Giant perfomance loss

[caiovale2011]

Look, I know this program needs a good performance overhead from the GPU to work properly, and that it depends on the game, pc specs, resolution and etc. But in most games i have almost a 50% fps loss when activating lossless !
I already made a similar post some days ago, but now I made some more tests:
RTX 3060Ti 8 GB
16 GB Ram
R5 5600

When playing God of War(2018), using DLSS performance on 4K medium settings, I got a stable 85-90 FPS. When turning on 2.1 LSFG 2x, the FPS drops to 50 FPS and ups to about 100 "FPS", witch without VRR is far worse than before.

The same happens with Ghost of Tsushima (90s FPS---> 55 FPS ---> 110 "FPS")
The same happens with Horizon Forbidden West (80s FPS---> 45 FPS ---> 90 "FPS")
And basically any other 4K game I tried on my TV.
I check the VRAM, using lighter games and/or lower texture setting, with no avail
I tried messing with all regular toggles in the right portion of the app, including HDR and Allow Tearing, with little to no difference to the performance drop.

Now, I will say, I tried using the most recent version of the performance mode in LSFG 2x, and It helps considerably. As an example, in the same setting God of War(2018), 2.1 LSFG 2x, the FPS drops to 60 FPS with performance mode enabled instead of 50 FPS, allowing me to try limiting FPS to 60 to get 120 Frame gen.
BUT, it stills very frequently drops from 60 FPS to the 50's, and the extra artifacts from performance mode are much more noticeable on a 4K TV right in you face, making a pretty so so experience.

Also, if I got something wrong, try not to be rude, I'm still learning hehe.

Native 4k is simply super expensive to interpolate. No way around it. I'd strongly recommend turning off the frame gen's performance mode, using LS1 to upscale, and shrinking the game's window to the lowest point you're comfortable with. 1200-1440p might still look good? Maybe test different sharpness settings too, see where your preferences are.

EDIT: Missed the DLSS part, maybe turn off DLSS and rely solely on LS1 for upscaling from 1080p or so. It looks better than FSR1 to most people, if you're worried about that. The interpolation's gonna hit your GPU way harder than DLSS can make up for, and you may even see an improvement to both visual quality and performance.

^^^ Yup. I know from experience that LSFG (without perf mode) takes up the majority of the computing budget on a 4060 at a 4k render resolution, i doubt your 3060ti would fare a lot better. Try DLSS Quality on either a 1440p or 1080p window and let LS1 scale it the rest of the way.

If your game supports window resizing in windowed mode, you can set "Scaling mode" to "Custom" and raise the scaling factor until you've got GPU headroom.

Thanks for the tips guys! I'm trying some new combinations from resolutions/upscalers/LSFG. Maybe I'll try making a new post with the results.

I currently have an RX6750 XT, which has frame generation and FSR in the driver itself. And it's amazing how well they work in any game. Frame generation only in DX 11 and 12, but the FPS gain is tripled in some cases. I tried some tests with the program's frame generation and I couldn't understand it, much less get an interesting result. I wanted to make it work in games that use 3 screens, Sims Race in this case, using AMD Infinity Eye, but the frame generation is incompatible.

The RTX 3060 Ti is better than the RTX 4060 in 4K, but both are not good for that resolution: 4060 is for 1080p, 3060 Ti is for 1080p and 1440p.

The difference is 5-10%, excluding outliers. Probably not enough to make a significant difference LSFG GPU utilization.

I got the 4060 to upscale/interpolate 1440p60 to 4k120 fluently at a mix of medium to ultra settings in FH5.

What you don't want to try is interpolating a 4k input with these kinds of cards. At that resolution you have to sacrifice too much in terms of quality settings.

You could, probably. But on something like a 32inch 4k display it would be silly not to scale 1440p to 4k, given the pixel density.
