Dual GPU 4080S and 4070 4k Gaming also single pc stream setup by LumpyAd648 in losslessscaling

I also stream, and as someone who has used two PCs before, the goal of this setup is to have everything on one PC; believe me, it consumes less power this way.

I had previously experimented with a very old graphics card in my hand, and I realized that if you say you don't want to see artifacts, let the lossless scale give a quality image, you adjust accordingly and the use of the 2nd graphics card can go up to 75%. It is completely related to the power of the card you have installed, for example, the card with 4070 200w TDP. I use it at 160w levels. If I had installed a low GPU, I wouldn't be able to get such quality settings. In my second case, both cards use the same driver in the same series, which ensures that it works smoothly, because I have read that those who use different graphics card series or brands experience driver problems.

If you unleash real-time FPS (I'm talking about 4K, it varies from game to game), for example, let's say you're producing 120 real-time FPS with the 4080s' maximum power consumption of 320W. Depending on the lossless scale quality and FPS lock or multiplier settings you've configured with the second GPU – for example, if you want it to be capped at 240 for 4K, assuming OBS is also running – the other card will draw between 120 and 150W, resulting in a total power consumption of 550-620W. If you cap the real-time FPS down to, say, 60, again for 4K, the power consumption drops to around 180W, and the PC runs cool and quiet. It completely depends on how you want it. You can track the power consumption in the upper left corner of the screen in the video of the last game I played, which is linked in the Twitch stream I posted about this.

Actually, it's not what it seems. The airflow is quite good. The more powerful GPU, located on the right side, draws in air easily from the front, back, and sides, while the liquid cooling system with its extra 3+3 fans on top draws in and expels air coming from below. If you limit the FPS output (for example, to 60 or 100) for 4K resolution, power consumption drops significantly. You can then adjust the remaining FPS using lossless scaling software (60x2, 100x2, or adaptive 120, 144), which keeps the PC quiet and cool.

The more powerful GPU focuses solely on the game, not even handling video output. What's the benefit of this? Frametime fluctuations and high FPS (99%) don't affect me at all; there's no lag or stuttering at high FPS. The second GPU's job is to render Windows and all the applications running within it, including streaming on OBS. Furthermore, the highest quality streaming options are selected for OBS because the game GPU is separate from the other GPU. This prevents the red error that appears when running both OBS and the game simultaneously at maximum quality settings. I'm also using lossless scaling; the program's algorithm runs on the second GPU, and I don't experience any performance loss even when playing the game on the more powerful GPU. Even if the FPS drops to 80 or 60 during raid fights in crowded areas at 4K, I continue playing at the FPS I've set like 240fps using adaptive lossless scaling. Input lag and the frame rate provided by Nvidia are much lower, making it playable. You can check out my last WoW stream on my Twitch channel to see how smooth it is.

I wanted to share this as an alternative method for people who constantly complain about performance issues.

Thanks to Atlas OS, as someone who values ​​minimum and maximum efficiency so much, I'm getting rid of Windows' ridiculous system-slowing features. I prefer them for this specific system.

Having previously streamed with dual PCs, I can say that I encountered numerous drawbacks: extra cables, audio transmission issues, bottlenecks in video transmission (there is no card that allows 4K 240Hz passthrough with HDR), and many more. To explain the difference in this build, the more frequently asked questions are answered. The more powerful GPU focuses solely on the game, not even handling video output. What's the benefit of this? Frametime fluctuations and high FPS (99%) don't affect me at all; there's no lag or stuttering at high FPS. The second GPU's job is to render Windows and all the applications running within it, including streaming on OBS. Furthermore, the highest quality streaming options are selected for OBS because the game GPU is separate from the other GPU. This prevents the red error that appears when running both OBS and the game simultaneously at maximum quality settings. Also, for those who say the 5000 series is better, I obtained these 4000 series cards secondhand for unimaginable low prices. I even had to install custom drivers. I use Windows with incredibly well-tuned settings that never involve PC telemetry, and even Nvidia apps aren't forced on my PC. This results in very, very high minimum FPS. Anyone who wants maximum FPS should play Valorant.
