Stuttering issues on a RTX 2070 Super and a Ryzen 7 1800X

[rapfamily4]

Hello,
does anyone else suffer of stuttering issues with a high-end PC?
I'm running the game on a custom fidelity (most of the things are set on low, though), and sometimes the game reaches 50-40 FPS. I also set the Vulkan API, but I didn't notice any significant improvement.

My rig is the following.

CPU: AMD Ryzen 7 1800X (3.6 GHz)
RAM: 16 GB (3.2 GHz)
GPU: Nvidia GeForce RTX 2070 Super
MB: Gigabyte B450M DS3H
HMD: Valve Index (set on 144Hz)

How can I solve this problem? Is this relatable to the rig itself or to something else?
Thanks in advance.

What headset are you using? Is your memory running dual channel.

I'm using the Valve Index, presumably on auto resolution at 144Hz. RAM is set on dual channel.

Is your RAM actually running at 3.2GHz? For myself and many others, getting the RAM to run at it's advertised speed is the tricky part of building a Ryzen based system. Check what frequency it's set to in the BIOS, try messing around with XMP/AMP settings.

I used CPU-Z to check it, and apparently the DRAM frequency is 1064.1 MHz.

I tried to enable the AMP (first time in my life) and the frequency changed to roughly 1600 MHz. It's still not 3.2 GHz. Maybe I messed up with something. I'll try that again.

EDIT: the BIOS charts say that it's now running at full frequency. I formerly checked just on CPU-Z. I'll see what happens in game and I'll tell you. Thanks anyway.

I believe your memory is correct when CPU-Z says it's 1600mhz. Since it's dual sides.


Don't run Half-Life Alyx on 144hz. I suggest to lower it to 90hz and see how that goes. Than if you want than u could try 120hz.

You can use a program like fpsvr to see your performance.

Ok, so the memory runs as it should. Today I learned something useful!

Uhm, I'll try to lower the refresh rate of the HMD. Thanks. I'll tell you if it works.

Ah, I already use FPSvr, and I got interesting results with that: sometimes the CPU chart goes crazy, registering with red spikes at a certain frequency. I don't know how to interpret those spikes, though... The GPU seems to work normally.

For me the game runs smoother and look a bit sharper on 90hz than 120hz. And I have a Ryzen 2700x 16gb ram and a RTX 2080

Woah, I never thought it would have been such an issue.

I'll tell you if it fixes anything. I can't play the game right now.

I also had issues with a 2070 Super and 3600x. I increased my ram speed and downloaded "Process Lasso." In Process Lasso, I set VR Server, VR Compositor, and a few other processes to "High Priority." Now it runs much better

Ah, thanks. I read you can set the priority through the Task Manager (Details tab, then right click on the application to set the priority). I still didn't try that. I'll tell you if it works.

i5 6600k running at a stable 4.7 ghz, 2070 super and 16 gb ddr4 3000mhz ram. Not much difference in stuttering between Ultra and Low. Later levels have become pretty much unplayable. I've tried all the tips to make it run better, ram is running dual channel at the right speed. Something strange is going on.

Performance felt better on this game with the 1070. I upgraded to 2070 for this game. I was looking earlier to upgrade processor as well as gpu upgrade was pointless but too many people are having the same issue over a massive range of hardware. I don't see how it's our computers.

I have the exact same. I started the game on a 1070 and was flawless but by mid game I got a 2070 Super and noticed some stutters but when I started a new game the part where you get the gun is a slide show and happens every time now. The rest of the game is 95% flawless but the game was butter smooth on a 1070

I have almost the same setup except I have 32 gigs and a 1070 TI It has to be an issue with those RTX's cause I'm not having any problems at all with my 1070 TI

Lower your FPS to 90. It's imperceptible the difference between 90 and 120, and the resolution will increase thereby increasing sharpness. Also, you have to remember that HMDs work differently than standard displays - then will only run at your set refresh rate and once it dips below (i.e. below 144hz in your case) then the fps HALVES, meaning there is no in between. So if you are targeting a very high framerate and your computer cannot cope, you will constantly see much lower framerates.
