Hi @Vrjssa, thanks for confirming the performance increase in the latest drivers using the F1 2017 profile. We are currently working with AMD to get an updated F1 2018 profile added to a future driver release.
@Hoo i know Crossfire is not easiest setup so i understand that Codemasters and AMD need time to develope a profile F1 2018. Until then i use F1 2017 profile with newes driver package. It seems to work fairly well for me. Bit of stutter and lag when play long periods but restart the game solve it.

If you need more information i try to provide it.

Guys, Nvidia just released a new driver (version 399.07 - published just recently). Quoting from their release notes:
"The drivers have optimizations for Battlefield V Open Beta, F1 2018, Immortal: Unchained, Pro Evolution Soccer 2019, Strange Brigade, and Switchblade. Application SLI Profiles Added or updated: F1 2018"

I makes me so sad to have to wait that long just because of  having an AMD based crossfire system :(

@Hoo: Great to hear that you're working together with AMD to optimize and create a native Crossfire Profile for this game. Thank you (in advance).

The 18.8.2 driver produces a significantly improved framerate for me without forcing F1 2017 profile.

2 x Radeon R290 in crossfire

18.8.1 driver
1080p High preset - single screen
Ave FPS 39
Ave frame-time 25.2 ms

18.8.2 beta driver
1080p High preset - single screen
Ave FPS 95
Ave frame-time 10.5

18.8.1
5760 - triple screen - Med preset
Ave FPS 19
Ave frametime 50.5 ms

18.8.2 Beta driver
5760 - triple screen - Med preset
Ave - FPS 65
Ave frametime 15 ms

18.8.1
5760 - triple screen - High preset
Ave FPS 18
Ave frametime 55ms

18.8.2 beta driver
5760 - triple screen - High preset
Ave 59 FPS
Ave frametime 16ms

So my FPS has at least doubled - even tripled in most cases from 18.8.1 to 18.8.2 beta driver with much lower frametimes too.

much much smoother and very playable in triple screen at 5760x1080  on an old I7-2600K with 2x290 in crossfire.

Very happy with that - I’m assuming there is a F1 2018 profile in those new beta drivers to get such an improvement ...

Profile is coming next driver release. Not this 18.8.2 beta yet. But clearly R290 cards benefit more Crossfire mode this release :)

Which track are you using for the High 1080p single screen? I have plenty benchmarks.

I saw improvements in the pre-release version going from 18.7.1 to 18.8.1

Just CBA to load 18.8.2 if I don't know what I'm testing against. I assume you are talking about the in-game benchmark on AUS cycle cam?

Yes - Australia - default cam choice = cycles between them.

Massive jump for me from 18.8.1 to 18.8.2 more tripling the frame rate at 5760 and more than doubling at 1080p.

Can only be some level of crossfire activation that has triggered that. Can’t imagine there is much more to come even if there isn’t an actual crossfire profile yet in 18.8.2 beta - are we sure there isn’t ?

Update. I downloaded AMD's 18.8.2 driver and ran some benchmark tests. Here are the results

Machine:
Cpu: Intel 6700K stock clock
32gb Dominator RAM
512gb Samsung Pro m.2 drive
2 Asus Strix ROG Rx-480 8gb Overclock GPU's
Asus MG279Q 2560x1440 144hz monitor

First test was run with Crossfire turned on

2560x1440 Ultra settings 50fps
2560x1440 High settings 76fps
1920x1080 Ultra settings  56fps
1920x1080 High settings 78fps

Second test was run with Crossfire turned off

2560x1440 Ultra settings 50fps
1920x1080 Ultra settings 63fps
1920x1080 High settings 102fps

Considering the 18.8.1 driver only produced 35fps in Crossfire mode with everything maxed and 2k resolution, I would say this is a marked improvement. I am sure once everyone (AMD, Codemastes) gets on the same page, I will see the 87- 95fps I see in 2017 with max settings and 2k resolution.

@BruceBass I don't get it - I just can't see any improvements for you between crossfire turned on and off. This is a mess. Crossfire is totally useless and in full hd (1920x1080) you get even better performance when crossfire is turned off! :(

Like I say, I saw the uptick between 18.7.1 and 18.8.1 in the pre-release.

Nothing to see here for the majority.

When I had Nvidia I never saw F1 2017 have SLI support and often single card performance trumps older SLI/Crossfire

There is a new version of F1 2018: it's 1.05 which solves all those frame drop issues.

Nonetheless crossfire scaling is still poor. Especially using TAA / TXAA drops performance towards single card setup :( Will next driver update from AMD fix this?

Try new drivers. Now it seems to be support.
Radeon Software Adrenalin Edition 18.8.2 https://www.amd.com/en/support/kb/release-notes/rn-rad-win-18-8-2
Support For

    F1™2018

Also if any help

This advice works and give still best performace 18.8.2 drivers. Not tested yet 18.9.1 drivers.

"try using the F1 2017 profile in the current AMD drivers. Our internal tests show significant performance increases when using crossfire with these settings. If you are still having problems then let us know and we'll run some additional tests."

Some improvements.

Radeon Software Adrenalin Edition 18.9.2

Support For
F1™ 2018
Up to 3% faster performance in F1 2018 using Radeon™ Software Adrenalin Edition 18.9.2 on the Radeon™ RX Vega 64 (8GB) graphics card than with Radeon™ Software Adrenalin Edition 18.8.2 at 2560x1440 (1440p).
