Extremely bad performance with certain high end ATI cards and Steam VR in Supercruise

Hello guys,

I'm getting extremely bad performance in Supercruise.

As you can read here https://community.amd.com/thread/198010 after a short time in supercruise, my frames are dropping way under 75 fps and tend to bounce around 37,5 fps. The judder I get when this happens is strangely smooth, but makes the game unplayable for me non the less.

In theory my system should handle the game quiet well in low to medium settings.

I expect this to be a bug in Steam VR and/or ATI drivers. If you are experiencing the same, maybe you can add a replay to the thread linked above.

Currently I'm using Crimson 16.3.1. I had the same issue with 16.3 and 16.1.

Before the 16.1 hotfix, Supercruise was bugged for me as well, but not with this new kind of weird smooth judder. With the older drivers the judder was way more intense.

It is really hard to describe, but the 'smooth' judder feels more like a lag of some milliseconds and not like the judder you get with quality settings to high in a Station or on the ground for example.

With this and the German report on the Fury X I'm going to jump ships. (Sorry I know this is of no help but made my choice easier and the 980 being mentioned in the requirement)
Have you had any response back from ED support. I would hope they have new spec AMD GPU's in the QA dept.

I hope with official Oculus support Elite is running better with ATI cards. But as you already said, better avoid ATI if you are interested in VR. Nvidia seems to be better supported.

im an advocate for whatever works best and back in the day was strictly an ATI guy. (they were from Ontario Canada, woo!)
However once AMD bought them out, i jumped over to Nvidia. I have had an Nvidia card from every generation since before the gtx moniker came about.
In that time (10+ years?) I have never had any issues with any games or launch day titles. That being said, I follow the steam forums pretty heavily with the trending games and there are two things that always stick in my mind...

1. AMD is usually a pain in the ass for so many people on launch (       driver support?)
2. if the game is nvidia game works, be sure its not going to run well on AMD for the first few months.

This has been pretty prevalent with late great AAA titles..

I also build PC's and do tech support for my business, in the last 15 yrs I have built 1 AMD based computer (FX 6 core) (cpu/gpu) and that is the only system I regret building. it doesnt even hold a candle to my q9550 nvidia mobo build...the single core performance of AMD is atrocious....

anyway call me whatever you want, i stick by Nvidia and Intel to have a smooth gaming and productivity experience.

Could it be a problem with windows 10 and the driver. I never suffered with the supercruise bug as I was using windows 7 and still am.
I have an AMD Fury (non X) and so far have no issues with any games I play. Saying that, i don't have a VR unit to test.

It's only if running through the dk2. There is no drop when playing on monitor. I tested in win 8.1 and 10 and tried oculus sdk 0.6.0.1 and 0.8 through steamvr with 16.3 driver. Win 8.1 and 0.6.0.1 is almost playable but still drops too far.

So I did a short run:

Performance still goes down to 37.5 fps.

But: Async Timewarp is awesome. It still feels buttery smooth and no judder at all. Out of Supercruise I get better performance than ever with SS 1.5. So performance still decreases over time but it is not that big of an issue until amd releases a fix.

Is Async Timewarp an option in 1.3? Did you have to update firmware? Asking bc i'm waiting for a deepoon E2, basically a DK2 Clone that even works with their drivers... and repped, of course.

ATW is automatically activated in the 1.3 runtime and I use the same firmware as before (dk2).

That's bad news. Couldn't try it myself on the R9 Nano yet, but was hoping with the 1.3 SDK the ATI Performance issue would be gone...

Checking for discounted 980 TI OCs now.


EDIT: Maybe this new driver is helping.

Crimson 16.3.2 seems to be working really good with SDK 1.3.
I haven't had any performance issues on the ground or inside a station. Supercuise is also stable at 75 fps.

Finally !
