getting really low fps on fortnite dx12 and dx11

[Darksider]

i got a rtx 4080 13980hx laptop at 2k resolution and get 60fp on dx11 and 45fps on dx12 ultra settings can anybody tell me if theres a fix for this or is the game to demanding

DirectX12 is more demanding than DirectX11 at high settings.

Is multithreaded rendering on?
Are you using dlss or ray tracing?
Have you tried at lower settings?

Wipe out the drivers and go download and install all the latest ones for everything...

Chipset, both GPUs, Audio, LAN, WIFI, BT, TouchPad, etc.

Then set NVIDIA as the default GPU.

Try a High or Very High Preset and see what difference it makes compared to Ultra.

If your Display supports above 60Hz be sure to set that in Windows (such as 120, 144, etc) and run games in Borderless Window Mode

If game offers DLSS, try using that to gain FPS

I find it funny that ppl ask questions about Fortnite on Steam
but who knows maybe it will be on Steam one day
I mean just look at Blizzard games who wouldve thought they would be on Steam only a couple of years ago

If updating drivers doesnt work, try disabling optimus. Depending on your laptop manufacturer, you should be able to do this in your bios. However, it would only be supported if the laptops display is directly connected to the 4080 and not the iGPU (you can figure this out by searching "(laptop model) disable optimus". Optimus is designed to switch between your dGPU and iGPU to save power. Unfortunately this is one of the main causes for low performance in gaming, as most games don't recognize this gpu switching resulting in unfavorable performance. If your laptop supports using only the dGPU, there are a few downsides to this:

Decreased battery life and longevity. If you game without your laptop plugged in, don't expect more than an hour or two of battery life while intense gaming.

If you do game with the laptop plugged in, it will draw more power thus, more power is being pulled from the battery and more power is being put to the battery (charging), and when done for long periods of time, your battery longevity will decrease. This means that when the laptop is not plugged in, you can expect the laptop to die faster. Usually this doesn't become a massive issue for a few months, but if you're someone who likes to have the laptop unplugged, I'd be cautious that.

IF, for some reason your laptop does not support disabling optimus. Some laptops have their hdmi and display ports that directly connect to the dGPU, so that would mean, if you have an external monitor, you can try plugging it in the laptop and see if that works. here is a possible work around. Like I said previously, if your laptops display is connected directly to the dGPU, disabling optimus is supported. If it isn't directly connected to the dGPU, then it isnt.


Note: I don't have all the information about this to give you, but a simple search on YouTube about optimus and how it works can give you many more answers than this text would. I've had to do this on a few of my past gaming laptops and disabling optimus in the bios was the only way to get the maximum gaming performance possible.

Here is a video explaining what I said (probably in a better way too haha):

I hope this helps!

no DLSS no ray tracing I shouldn't lower settings I'm running it on a 4080 I should be getting at least 100fps with 95% gpu usage

Only 100 FPS ?

For those specs @ 1440p it should easily be like 180-250 FPS easy.

Monitor the CPU & GPU temps and see how hot it gets.
Most of these Laptops thermal throttle like crazy if you don't know how to make all sorts of advanced settings changes to the Laptop.
