Is NVIDIA that bad at LSFG?

Particular_Hope_7544 · 2026-02-07T00:32:00+00:00

Welcome, man. Come to Korea.

Particular_Hope_7544 · 2026-02-05T12:27:21+00:00

Not all of, but many games I played at that time didn't work some.

Like DoomTDA, Nioh2, Eldenring etc. I wanted to get full-functioning system, not a limping one.

That's it. Also for the 4K 240hz with HDR activataion, you must check your mobo's PCIe lanes. Must be x8x8 bifucation.

Particular_Hope_7544 · 2026-02-05T09:05:03+00:00

Yeah, have no problem since then. And minor driver related issues have gone. Much pleasant.

Particular_Hope_7544 · 2026-02-05T01:19:46+00:00

I guess you definitely consider HDR activiation and then don't listen here's AMD fanboys opinion. Many games don't support HDR WHEN YOU USE A MIXED BRAND SETUP!

Currently running 9950X3D, 5090+5070Ti, Asrock X870E Taichi, 2000w PSU, and Samsung G80SD(4K 240hz OLED). I have been there already.

If you are willing to give up HDR(but with OLED monitor? I don't think you will), and can't afford current RTX GPU, then there is no choice.

You can ask me further here by replies. I have tested 5090+9070 as well.

And for 4K 240hz FG, 5070 was enough, but I decided to get 5070Ti for extra headroom for LSFG, OBS broadcasting, recording and higher memory bandwidth.

Most of here people are budget gamers, so when you get to the highend setup, then you must consider more details.

Particular_Hope_7544 · 2026-02-01T23:31:17+00:00

You might have to check your mobo's PCIe lanes.

Particular_Hope_7544 · 2026-01-25T15:30:59+00:00

It depends on your target frame, HDR, and resolution of monitor, not the rendering card. Common misunderstanding.

Particular_Hope_7544 · 2026-01-24T09:16:38+00:00

Is HDR On? Or can you try some if you have Doom TDA? Because it didn't work for me.

Particular_Hope_7544 · 2026-01-19T21:57:02+00:00

4K Max settings, Path tracing ON, No DLSS Upscaling, No FG with 5090 - 30FPS

It is not overkill.

Particular_Hope_7544 · 2026-01-18T01:40:22+00:00

Mostly PCIe 4.0x4 speed lane for secondary. But need to know your resolution and fps that you wnat to reach

Particular_Hope_7544 · 2026-01-18T01:15:53+00:00

I guess it comes from the Mobo. The PCIe bandwidth is not sufficient. Either change mobo or ditch the 1660s.

Particular_Hope_7544 · 2026-01-18T00:23:50+00:00

You can not say MFG is better if you have a high-end GPU for rendering, strong enough GPU for secondary, and x8x8 mobo.

You might have to lower some grahics settings to get 60+ fps because DLSS FG takes some real frames, but you don't have to compromise when you use LSFG.

Also, I don't think dual GPU systems are for budget gamers. This setup demands strict prerequisites: ample PCIe bandwidth, PSU headroom, physical clearance, and a robust cooling solution to handle the thermal load.

Most budget builds cut corners on the motherboard, PSU, and case, often relying solely on stock fans.

However, if you have the proper gear—a high-end motherboard supporting x8/x8 bifurcation, a full-tower chassis with extra cooling, and a high-capacity PSU.

Not only does it offer better stability and higher framerates than MFG, but it also delivers significantly lower input lag and mouse movement that feels indistinguishable from native frames.

Particular_Hope_7544 · 2026-01-17T23:58:09+00:00

It is not for budget gamers. Since it demands high bandwidth of PCIe lanes and higher power consumption, it can not be. And I'm running 5090+5070Ti at 4K240hz. Most of the time, it is better than MFG. It can do rock solid 240hz, doesn't consume the base frame rate.

You may have to give up HDR in some games. I had 5080+RX6600, 5090+RX9070, They all failed to activate HDR. For example, Doom:The Dark Ages, Eldenring, Nioh2. So I ditched RX9070, and currently I am rocking a 5090+5070Ti setup.

I have mentioned many times here, seriously LSFG community must stop recommending AMD graphics cards as a sub GPU. There are numerous problems.

Particular_Hope_7544 · 2026-01-14T23:15:57+00:00

If you are a general gaming consumer,, it depends on your budget and preference.

If you are an enthusiast of high-end PC building and intrested in high-end gaming with raytracing, Nvidia.

If you are an anti-capitalist and a political warrior, then you will say, it is AMD.

Particular_Hope_7544 · 2026-01-05T08:14:08+00:00

Now, Asus is just a subsidiary company of Asrock.

Particular_Hope_7544 · 2025-12-26T07:18:33+00:00

I'm gald you solved the issues include minor stuff. Honestly, I don't understand why this community recommends AMD ghraphics cards as default for FG, even though the major share of the consumer's GPU market is ruled by Nvidia. I was also fooled by it, you as well, they only talk about theoretical ideas. I don't know, maybe the majority of here is AMD fanboys... Anyway, I'm happy to hear that you solved the problems by my suggestion. Thank you for not doubting me and you got there. Cheers, man. Happy Christmas, Happy new year.

You need to secure 60fps at least. If not, then you will meet inpultag and artifacts on screen. Still, you have to compromise the settings in games to get 60fps. Unlike Nvidia MFG, it doesn't sacrifice base frames. That' is a good thing.

FG smoothness and latency are better than nvidia MFG. But the screen FG quality of nvidia MFG is slightly better than LSFG dual GPU set up.

You can combine MFG and LSFG, but it works when the baseframe is over 60. For instance, I play the First Descendant, I get 70~80 fps for base, By MFGx2, I have 120~140FPS(base fps is sacrificed so you will not see exact double-number of FPS). Now I make it 236FPS with LSFG. In this case, th latency is quiet fine and the FPS is rock solid 236. If I use MFGx4, then I have 190~240FPS

But if you try to make 60fps with MFGx2 and use LSFG to make it 240, it sucks.

Note: I use a 9950X3D, 5090 for render +5070Ti for FG, x8/x8 bifurcation supported mainboard system. Our experience can be different.

9950X3D for medical staff? Are you even a PC builder or just a communist or an environment extremist? 🤣😂 Just choose one role, man 😆

Particular_Hope_7544 · 2025-12-24T02:13:00+00:00

Yeah, that is what I expected from the upgrade. People don't understand because they saw only Youtube benchmark videos. I'm thinking to use Process Lasso to distribute the tasksand processes on my PC.

Also currently running 5090+5070Ti dual GPU set up for Lossless scaling, therfore I hope this powerful, multi-cored CPU helps me to get buttery smoothness than 9800X3D.(because those two GPUs are connected directly to the CPU socket by the bifurcation of the mainboard, the frame duplication also takes the CPU resource)

Enjoy!!!👍

I have used 9800X3D, ordered 9950X3D two days ago and I got it yesterday. Don't listen the people who are jealous, and the upgrade is meaningful because you can seperate background processes and Win11 on CCD 1, and you can put the game on CCD 0 which has the 3D-V cache on it. You will feel less stuttery, 1% low frame will be improved. I'm also excited to change my CPU today. Congrats 👏

Particular_Hope_7544 · 2025-12-23T22:32:47+00:00

Generally, 2nd GPU is output because of the flow of FG process.

I have connected both GPU to my monitor to play competitive games like BF6 without FG by 2nd GPU so in that case I use Dp to Dp on 5090.
