is it safe to run this on a gtx 1650 laptop gpu? as someone else told me its not good to run fsr and frame gen on gpus that dont really support it because of cuda and rt core being different or smt.

it works fine. just use the performance mode of 2x or 3x mode

your game must be set to windowed and the scaling type (like fsr, etc.) is only needed if you have lowered the game's resolution as well

[jaunty lake]

okay thanks

[jaunty lake]

I tried it out and uh not only do I get less base fps when I turn it on but for some reason when I play games I hit people on my screen but I don't land shots so I think that might be a huge delay so maybe gtx 1650 isn't good enough for thus app

Oh n the lower base fps makes it so I get like no fps gain with it on

Will try with dx12 in fortnite n say my results later

scaling has a gpu impact and so does lsfg
for scaling you have to lower your game's resolution
frame-gen you should toggle performance if normal is too much
enable "draw fps" in ls to see what ls is rendering at
also make sure to cap your fps. you need to set it to something that your game can run stable at while using lsfg (don't run your gpu at 100%, 90-95% is fine. 2x needs a maximum fps cap of half your monitor's hz (like 60 fps, 120 hz) and 3x a third of your monitors hz (like 40 game fps, 120 hz)

A GTX 1650 Ti should be plenty for LS to work. Read what Warriorwolf posted, and also use MSI Afterburner's overlay to monitor GPU utilization. I would reccomend to adjust settings accordingly so that GPU usage never goes above 93%, and your base framerate pretty much never goes more than 2 below the cap.

[jaunty lake]

Yeah I did all of this and also tried the other option the reduces input delay

[jaunty lake]

See funny enough in my test with fortnite performance mode the gpu never even got to 80% when using lossless scaling with frame gen

Also I have a 1650 not 1650 ti

[quartz lantern]

Oops

So then the question is what about VRAM and CPU usage

[jaunty lake]

So gpu usage stays around like 60-70 ish as for vram I forgot ill try again and let you know but I don't think it was max either

[sand nimbus]

found the solution yet?

i have an issue with this too, in my laptop asus tuf f15 with gpu gtx 1650, whenever i try to run the scaling method on lossless scaling, it doesn't work, in fact it just make the fps go down even further...

[jaunty lake]

Hi sorry for the late reply but I'm still testing it around and

for gaming wise best thing to do is just not use it for like multiplayer games or games that u need low latency on with our gpu atleast, when u was testing it on fortnite I was being hit by the others and on my screen I clicked when my crosshair was on their body but it would just not hit them possibly cuz the delayed image

As for stuff like anime and some old story games n all it's w

Like only use it if ur doing a task that doesn't use ur gpu that much or u don't mind delayed images

Also how much ram u got and v ram

Sorry for my bad English I wrote this in a rush

[sand nimbus]

ram 8gb, vram 4gb gtx 1650

So here is how frame gen works and why you are experiencing bad performance. CPUs feed data to GPUs that then compute and produce frames. A slow CPU will not be able to feed enough data to the GPU and the GPU will then be bottlenecked, resulting in a low GPU utilisation (%). Frame gen takes advantage of those free resources and uses them to compute another frame inbetween, while waiting. Now, what happens when you use a GPU that is not being bottlenecked? It gets fed data from the CPU and is working as fast as it can, but you also ask it to work even more and to compute new frames -> lagfest. How to fix that? Make sure the GPU has free power for LSFG by:

1. Capping FPS. - If you can do 60, cap to 35-40 and interpolate to 70-80.
2. Reduce video settings, especially those that use GPU.
3. Reduce the resolution and possible upscale if the CPU can handle upscaling.
4. Turn on performance mode on both upscale and FG.
5. If on laptop and you have access to a good (AMD usually) IGPU, offload the FG to the IGPU and continue pushing the eGPU to its max when running only the game.

By following these tips, you should get an acceptable performance boost out of LSFG. How much that would be and if you truly reach 2x and 3x will depend on your PC and game you play.

Unrelated to FG, 8gb if ram is quite low and most likely contributes to a lot of the stutters, since when it overflows, the data is read from a much slower disk.

Ah i see thanks for the info man
