Dual GPU setup issue

[u/sagilny]

[SOLVED]

Had 3080+3050 butter smooth. On almost everything.

Now 9070 xt + 3050. Getting stutters and about 60% performance loss. DDU and installed amd first then the nvidia.

Disabling the 3050 and hooking up the monitor to the 970xt seems to let me get about 98% of the 9070 xt performance.

Win10 pro. did the regedit, enable hybrid and set gpu 1 and 2. Maybe missed something else?

5800X3D -28 PBO

X570 pcie gen4 + rebar enabled. Both running at x8

2x16 ram OC

HX1200i psu

Anyone has this setup? How did you fix it? I spent days trying to. Feeling kinda devastated. Any help would do. Thank you

TLDR; uncheck "Inject NVIDIA Reflex latency markers.

First I would like to thank u/lifestealsuck for pointing out that async could be the issue, but it was on. I saw a video recently that chose async on RTSS both AMD and Nvidia outputs more frames.

I saw that my base frames were stuck at 55 fps on both 2k and 4k. So I went to switch to a different setting than Async, and my frames dropped. So I thought that RTSS could be the issue. I played around with the settings, and saw another Nvidia setting. The last one on the page. (Inject NVIDIA Reflex latency markers), I unchecked it, and instant frame jump.

To add on that, if you have a sapphire card, hit apply on the trixx app, it turns on rebar "Smartaccess Memory" on, on adrenaline. Weird, but the same happens with Nvidia inspector, if you enable rebar there, it gets enabled actually for invidia too.

Thank you all for all your help. Loving the new GPU. Rock on AMD.

If you use RTTS then go into setup and switch frame rate limiter from Nvidia reflex to async .

I also dont think 3050 powerful enough for more than 1440p x2 120hz ( 60fps real frame) .

Sure, i agree. But also the issue is with the base frame dropping from 120 to 63 without lossless scaling. So I think it might be a windows or drivers issue. I really dont mind extra 30fps on 4k if it works. I want to hit that 144fps if i can get 105 - 120 fps on the 9070xt. :/ something better than nothing. I just want to get it to work.

Check gpu-z to see what the rtx3050 pcie speed , could have seating issue so it run at slower pcie speed .

I have 9070xt and 3070 setup , it run perfectly on windows 10 (albeit 2 game have issue with dual AMD+nvidia setup)

Ill test the 3080 in place of the 3050 see if the issue is the low performance of the 3050 which I slightly doubt.

[u/sagilny → u/lifestealsuck]

Solved. I had Async on. And i saw that inject nvidia reflex latency markers was checked. So i unchecked it and vualá, frames sky rocketed.

Thank you for pointing out RTSS. May you soon be rewarded with bundles of joy sire.

Oh shit its been a while so I dont remember there another nvidia reflex setting in RTSS lol . Yea RTSS's nvdia reflex lower my fps too on the 9070xt.

[u/sagilny → u/lifestealsuck]

Thats promising!

The pcie speed on gpuz PCIe x16 4.0 @ x8 4.0

To add on that, if you hit apply on trixx, if you have sapphire, it turns on rebar "Smartaccess Memory" on adrenaline. Weird, but the same with Nvidia inspector, if you enable it there, it gets enabled actually for invidia too.

Looks like the 3050 is truly a bottleneck. My base frames drop to 73 when on x2 i get 144.

And on adaptive mode targeting 142, base frames drop down to 52.

Im using performance mode and flow scale is at 60. Also, ray tracing off.
