I just use the default value but it seems like it works for some by tweaking it.

Hey Matt.

First of all - thanks for all your help.

I am now getting phenomenal performance in WZ. With Texture Resolution at Very Low, but with other values at High and Medium, with full AA on, I am now averaging between 200-240fps no matter where I am on the map. Literally as good I could possibly hope for considering I am on a 240hz 1080 monitor. I achieved this by using a lot of your OC values and tuning my Ram to 14-15-14-14 3400MHZ on my Trident Z. It's silky smooth.

However, I have noticed that my CPU temps do get dangerously high after awhile in WZ. I hit 82 after about 15 minutes of play just now. Is this safe temps for my 5950x or would you recommend lowering some of my OC values?

@LtMatt how high in the rumour mill is a 6950?

Haha it wasn't Matt. I love The Godfather, but having the same avatars is really confusing.

Duckwave · 24 Jan 2022 at 00:37

Finally! @LtMatt

I messed around with the video memory scale and changed it to 1.5. That has completely eliminated the stutter when I raise my Texture Resolution to Normal. Slightly lower FPS, but still pure silk.

This is by far the best experience I've ever had with WZ. It's finally a joy to play!

Can you get 3600Mhz CL14? Probably with the right voltage. I'd aim for that, if possible.

82c is high, but is safe. What cooler are you using? What PBO/Curve Optimizer settings? 90c is the throttle temp, stay at or below 85c and you are fine.

I see 70-75c at most in Warzone, generally 60-70c. with a 360MM AIO Arctic Freezer.

The HD6950 went legacy in 2013 mate.

Good news, but I'm surprised 1.5 even does anything to be honest. It does not make sense considering what the value is supposed to do, but if it works who cares! :cry:

Here's some COD Vanguard footage I captured at 4K, using competitive settings (shown at the start of the video)

I copied your PBO settings mostly, but a little less on the boost - 50mhz. I also didn’t use MPT and I couldn’t get anywhere near your minimum clock speeds in Radeon. I’m at 2300-2400. Core 10 failed at one point so I reduced the neg a little bit on that to -20. No crashes since.

I’m running on air - Dark Rock Pro 4.

My CPU Temps never exceeds 75c when I run Cinebench R3.

Lastly, I suspect the 1.5 value might just be defaulting to 1, but it’s running perfectly now so I’m reluctant to change it. Same with my RAM OC. I’m not sure anything is gonna give me better frames than current. Lows of 190 in Capital with Texture resolution set to normal.

Yeah if it's working good, don't touch it.

If I had to make any recommendations:

Aim for 3600Mhz CL14 on your memory
Use an Arctic 280/360/420MM AIO and your temps will improve, it will also allow your 5950X to boost higher. (see my video above for temps and clock frequency)

If you want to keep your air cooler, lower scalar to x1, reduce TDC/EDC to somewhere between 100-125 range and that might lower temps a little. Your current temps are safe though, so no harm keeping it at that, just if you want to improve them...

I just setup 2 monitors to make like easier while gaming and looking at Tarkov maps/discord etc.
I have -

6900xt

LG - UltraGear 27GP850 - @ 180 hz 1440p (going to check if this is the issue in a second as it classed as an oc) 165hz is base stat
ASUS TUF Gaming VG259QM 25" up to 280hz 1080p screen

The main screen is the 27" Ultragear which i can change the refresh rate as i wish anything up to 180 hz
But the second monitor will only show as 60hz capable nothing else to choose (was fine @280hz when connected alone)

I have both screens connected via DP cables and latest AMD driver (well 1 behind)

both my boys have dual screens and they are 1080p and 1440p they have no issue selecting which refresh they want but they use Nvidia 3070s

I have tried turning adaptive/freesync off on both screens and doesnt make a difference, this install is a new clean install from only a few days ago (spring clean).

Any help advice? i will go check the second monitor to make sure OSD is set right and not doing some weird stuff too.

FIX
ok i will write this a second time as the forum didnt remember what i typed for some odd reason.

So i went to display settings and made sure the correct screen out of the two was selected
scrolled down to advanced display and selected it
in here i could see the current refresh rate but couldnt select any other so stuck at 59hz
in here i clicked on display adapter properties, pops up an old school window
under the monitor tab i was able to see all refresh rates from 50 to 280 selected the one i wanted and now its all working correctly.
So the initial refresh setting page isnt showing what actually available until you got to the older display settings tab, bug in windows 11 ?

Glad you fixed it. My first suggestion was going to be check Windows Display Properties and select the correct maximum refresh rate.

Might want to check Radeon Software > Display sub-menu to ensure you have 4:4:4 Full RGB and either 8/10Bpc selected for both of your individual displays, depending on what your displays support.

Thanks i have those set correctly and alls working now, appreciate the response

Yeah, I would like to upgrade to an AIO at some point, but I've pumped a lot of cash into this already, so I need to give it at least 6 months I think

lol

I used Ryzen Calculator to mess with my RAM timings. I could go only get down to 14-14-14-14 at 3200mhz according to that.

Why do you think some people get better performance out of lower video memory scale values? Isn't it allocating the amount of VRAM to use? I always had mine at 0.85 or 0.55, and that's why I was stuttering. I would never try Very Low texture resolution so that's why it took so long to find the culprit.

What memory kit are you using? It's highly likely it'll do 3600Mhz CL14 if it's Samsung BDie but you might need to increase memory voltage to get stability at 3600Mhz.

It sounds like that is what is happening, but why that happens I've got no idea. I would have thought lower values would fix it, not higher values.

G.SKILL 16GB Trident Z Neo DDR4 3800MHz PC4-30400 CL14 RGB Dual Channel Kit (2x 8GB)

Thaiphoon Burner tells me it is Samsung B Die.

It'll do 3600Mhz CL14 easily, and might do 3800Mhz CL14 if your 5950X is happy at 1900Mhz infinity fabric clock speed.

Is this something you could assist me with? Or do I just change the first 4 values to 14 and then turn up the voltage?

Haha.

Yeah, to be clear, I'm really not great with this stuff. It's my first ever build.

Not sure whether to stick with 240hz 1080 or use my 144hz 1440p monitor now.... hmmm.

Try them both and see which one suits better. High refresh is ideal for FPS shooters, but 1080P is quite a low resolution so you'll always have the GPU performance headroom to move into 1440P easily.
