Considering upgrade to amd radeon r9 290x crossfire

[electricsheep26354]

Has anyone managed to totally iron out the crossfire issues with Skyrim and ENB?

The performance of the new r9 290x cards in crossfire is fantastic, but from what I'm reading there are many issues with ENB and crossfire

Has anyone tested Skyrim ENB with these cards in crossfire successfully with latest ENB and a high quality preset, or uses a 7xxx series card in crossfire - please share any results or feedback you may have

I am probably mad for even considering this move but the benchmarks are very nice...

I'm guessing you'll get a similar problem like myself, currently wracking my brains to find solutions about crossfire & skyrim. They just don't want to work together properly . You maybe a lucky one though where it does work I dunno. I have a ati 6990 and considering when do get around to replacing it in a year or more I shall go back to Nivida because AMD/ATI cannot make drivers to make the lower costs worth getting sometimes ...

Thanks for the feedback - looks like crossfire is no-go then for ENB - shame

I own crossfire 3x 7950, @ 1000 mhz cpu 2500k @ 5g, 8gb ram,
2x 7950 crossfire
dof creates problems of focus, it should be kept disabled
temporalaa if enabled disable second card

3x crossfire 7950
temporalaa if enabled, disable the other card

with 3x 7950 and truly a sight not ever go down below 60 fps with all settings enb to max

From what I understand, you just have to have the right crossfire profile enabled. I've heard Assassin's Creed: Brotherhood or Fear 2 work with ENB. I haven't tested myself, but it should be doable. I've seen on several people's signatures 7850x2 or other crossfire configurations so it definitely works. TAA doesn't work on multi-GPU setups I know though. Other than that, it should work just fine.

And yes, those cards are amazing. I have a single R9 290 and, while my overall FPS didn't really increase in Skyrim, I can keep throwing more and more quality and hi-res textures at it and it doesn't skip a beat. I increased the memory clock speed on my card by 15% last night and that did give me an fps jump of ~5-7. Core clock and voltages still sitting at stock though. You might wanna save some money and get the 290 instead of the 290x and then do a bios update from Asus or I think XFX for the 290x and turn your 290 into a 290x (exact same PCB, just some shader units disabled in the card bios).

I have 2 290x.

They flat out do not work in Crossfire. I get like 20 fps with Crossfire enabled. I have no idea how to set up a profile for them either as the latest driver do not support this.

I did actually try 2 x 290x in crossfire but couldn't get any satisfactory performance with Skyrim so took them back and bought second 780ti - works fantastic no SLI issues.

I also have AMD Crossfire, two R9 290X's and the performance hit in enb modded games is extreme, 50% or more. Sometimes CF is not working, in old gamebyro engines (Oblivion, Fallout3) needed special CF profiles. Skyrim profile does a great job in enhancing performance with them, but also makings things workout diferently, like overbright, flickering etc. So the game must be handtuned to look right.

I now have a beautifull enb present for Skyrim running from one of the great enb modders "Woods" and the perfomance hit is severe, just 20-30 fps in 3840x2160, 50% hit at least, with just only smaa.
The present is based on enb.251 and have many things enabled (SSAO/SSIL included). I have not discovered yet what causes the heavy performance hit. Crossfire is working though (enb. DOF still can't be used).

Allthough they are great performers in allmost every game, they still have many issues with enbmods, flickering, DOF issues and performance.
The same counts for ID-tech games modded with SIkkmod's shaderenhancements where optimisations break HDR. And cat. AI must be disabled, hence CF is disabled as a result.
