Chill causing Water Texture flicker  on The Witcher 3: Wild Hunt. - Now Fixed in Adrenalin Driver.

Here Is a Video testing this issue on AMD Crimson ReLive 17.8.2

This video contains some flickering water textures. It is unlisted on Plays.TV.

colesdav - Witcher 3 17.8.2 Chill in Crossfire Example 1. - Plays.tv

The Witcher 3 runs great for me allowing 4K Gameplay on Ultra at ~ 75FPS with Dual R9 Nano on i7-4790K and FreeSync using FRTC. .
It is great to see Chill in the game and supporting Crossfire.

However there are two issues with Chill in 17.8.2 as in 17.7.2:

1. Turning Chill on causes flickering water textures, most noticeable when the character is stationary and Chill drops to the lower FPS Limit of 47 FPS in my case.
2. Turning Chill on sets the upper FPS limit at 60Hz when the character is running/moving/active. I think it should set the upper limit to the Monitor Refresh Rate ... in my case the monitor refresh rate was set to 75Hz.

Thanks.

Finally here is a video of the AMD Crimson Settings used:

If the above videos from 17.8.2 are not enough examples, I have lots of examples from 17.7.2, they are shot during daylight/dusk in the game and show flickering better.
I have set those as unlisted so ... I can provide link here is anyone wants.

Thanks.

Here is an example running 17.7.2 in daylight. If you look at it carefully you can see the water textures flicker when the character is running or stationary with Chill on.

Water Texture flickering stops with chill off.

I just tested AMD Adrenalin Radeon Software Version 17.12.1 with the Witcher 3 in Crossfire with Dual R9 Nanos on i7-4790K 32GB of Ram 1TB SSHD.

The Crossfire Flicker on Water Textures appears to be FIXED

Thanks to AMD and the developers for fixing this issue.

FreeSync and Vsync off.

Crossfire enabled.

Default Crossfire Profile.

However Chill Targets are broken.
@1080p with the Min Chill Target set to 45, 60, 75 with the max Chill target at 120.

Standing Still min = 45, 60, 75 as expected.
However when running with Chill enabled the FPS never gets more than 15FPS higher than the min target.

i.e. 60,75,90.
With chill off the FPS when running goes higher.

-> Note in this case the mouse input was not increasing FPS.
-> Keyboard only input FPS is limiting to 15-20 FPS higher than Chill Min.

Similar behavior is seen at 2K and 4K, although the FPS offset seems a little higher at about +20FPS over Chill Min.

Unrelated to chill, The performance Overlay is far too small at 2K and 4K,

Also if you are running crossfire, you need to be able to see see performance figures for all GPU's to know exactly what is going on.
I guess that is a separate thread.

Thanks.

Here you can see Chill is broken in the Witcher, Crossfire off. FreeSync Off. Chill Max Target is not honored. Similar behaviour on evey game I have tested so far.
Therefore if you turn on chill, you get degraded performance. 
Way to go...
Let me know if if you cannot see the video.
I had to upload the video to my Google account because it was too big for Plays.TV.
The video is unlisted and I will take it down once this gets fixed.

Bye.

Here are a couple of videos for you to look at regarding chill with Crossfire off if you are interested.

colesdav - Testing AMD Adrenalin Rose on i7-4790K with Triple R9 Nano's. Adrenalin Rose Driver uninstalled. Windows 10 6…

Chill is broken on my system.

Never see more than 15-20 FPS above Chill Min Target with the Adrenalin Rose Driver.

You might have this working on RX Vega, and I hope so because I want to see AMD successful and Vega needs Chill to work to keep power consumption down.

But on my R9 Nano's it is busted.

I will go look see how it runs on a machine with similar specifications but with a single R9 Nano and i7-4770K. on Windows 10 and Windows 7 next.

Updated this thread to explain the following.
(1). Water Texture Flickering in Chill in Crossfire is fixed in Adrenalin Drivers.
(2). I had an issue with installation of driver from 17.11.4 -> 17.12.1 where turning Chill on, mouse not was not increasing FPS at all. Using DDU to reinstall the driver fixed this issue. Mouse input is increasing Chill FPS towards Chill Max Target value now. Since this was a driver installation issues I removed those videos.
(3). Keyboard only input FPS with Chill turned on never increases FPS by more than 15-20 FPS above Chill min.

This thread is now closed. Please see Could AMD please add Keyboard and Mouse input Weighting sliders for for Chill in Adrenalin Driver?
