AMD crossfire makes it worse? or am I missing something

[76561197992631699A]

if you came to say "crossfire is old tech ahyuk" pls get out

I literally had another gpu laying around and thought hey i might just drop it in (sorry plebs)

running 2 rx 470 4gb, tested and working well in gta V + crossfire
ryzen 1600, b350 board

I'm asking because there was an official crossfire profile / support?

i tried the default setting and 1x1 and its basically the same, I get flickering and about half FPS than using a single card

Yes, this game does not support crossfire connected GPUs. When you use it in crossfire, the game causes video artefacts (flickering).

thank you, just making sure if i should keep trying or not. it was claimed on the "crossfire wiki" Elite was doing well.

unfortunately nvidia sli and amd crossfire are not worth for gaming since most games does not support it or very poorly at least as said above in the case of E:D you'll get flickering.

weird.... used dual 290x, and now dual gtx 1070 cards and havent seen any issues as long as vsync is enabled anyway, and single or dual card, the taring when rolling the ship is enough that.. i prefer to just leave vsync enabled.

if you have a problem with crossfire with a specific game, try RadeonPro, you can find it on the Guru3d forums, you can use it to set a crossfire profile for the game.

one thing to note, you can have issues if you havent installed a driver that has crossfire profiles included, sometimes that means installing an older driver then updating to the latest driver, its not as bad on nvidias side, im not even running matched 1070's, ones a mini, ones an AMP Push The Limit 3 slot card... and, again, no problems with flicker or negative scaling at 4k.

i have had no issues with elite and cf/sli, lucky or whatever, also, core systems used.. amd fx 9370, and intel xeon x5675@4.4-4.65ghz, the only flicker and taring issues i have ever had with elite are when i disable vsync, and... thats regardless of single or dual cards being used...

i would suggest testing some older drivers, then work your way forward till you find a problem, its annoying but, the reason i moved off amd was because they broke the ability to adjust fan speeds without the driver bouncing the card between 3d and 2d/video decode clocks constantly, over a year of having to roll back to the same old drivers if i didnt want to edit my videocards bios..

you may find that, older drivers may offer the crossfire profile or a working one, that newer drivers for whatever reason lack... again personal exp with amd drivers... so often they make great hardware...then stumble on the software side... :/

anyway, good luck.

That's great to know, thanks! The last time I saw an SLI discussion here was several years ago, that included planetary images flickering, and general SLI problems with this game, that were fixed by disabling it.

this is why i put a little disclaimer in the beginning. I literally have it laying around, and I popped it in for literally nothing. I am very aware CFx or SLi are worth it

this reply is very much appreciated.
the 470s when not in CF can run on 570 drivers on stock bios, and I use bios mods because mining cards have bad power limit settings, otherwise they outperform OC'd rx580s (well, limited by thermals anyway)

they do not work though as stock bios 2x rx570 driver-wise (windows issue methinks because same card), but 470 drivers custom bios CF works dandy

I tried Vsync and different CF methods (1x1, AFR compatible) but only in the adrenaline App, does using radeon pro make a difference?

damn i wish you could just load in custom or known working CF profiles....I am aware they get jumbled between driver versions.

And what do you mean fan speed issues? just curious, why not just set a custom curve in Afterburner?

with the 290x and some other cards, when they forced wattman on everybody, any changes to the fan speeds or clocks, anything in those tabs, would cause the card to cycle between all clock modes, 2d, video decoding, and 3d rendering over and over, causing the screens to flicker on and off if you had more then one...or one at higher then 1440p or 1600p...

they never fixxed wattman on those cards afik, instead they did what we spent over a year asking for... and just let the old card users, stick with the old tools and added back the code to support those tools to the driver files for those older cards...

for over a year they just let us run a user created 3rd party app to force our videocard to run at 3d clocks all the time or, edit and flash the vbios to suit our needs... neither are ideal solutions.

i dont remember if amd use internal bridges or not on those cards, either way, radeon pro very well could help.

also make sure the games set to max perf mode not some stupid power optimized(amd and nvidia love to default to low power use mode, rather then optimal perf or adaptive modes...again...another thing thats annoying as balls about the modern era...

it should just work in cf if the cards have the same vbios, and that should work with elite, but again, it can be... hit and miss...

what you could do, is check for the latest drivers that specifically support dual gpu cards like the x295 i think it was, since thats, afik, have yet to be relocated from supported to legacy.... when amd put GNC on legacy status though...omg is the salt going to flow... and i see alot of people either switching to linux or selling them cheap...hopefully both...(honestly, after testing..im gettng close to switching to solus linux with steam... tired of MS updating drivers and crap in the background breaking my system till i restart, reinstall a full driver, then restart again... pita..)

im surprised at the flickering issue...


https://amdcrossfire.fandom.com/wiki/Crossfire_Game_Compatibility_List

and yeah, my exp matches what that says, almost doubles perf, sometimes more depending on how gpu limited you were...

like i said i would suggest trying drivers that specifically support the 295 in hopes they would include profiles...

wish these companies would just put out tools to create/share/update such profiles honestly... nvinspector was needed for a few games back in the day to change the default sli profile, that gave....less then ideal results.. forcing the mode where each card draws 1/2 the screen.. lower max fps..but the lows went from te teens to the 50's.. so...yeah... much smoother... (same trick worked on amd cards using tools to edit profiles...later replaced by radeon pro, thats, genuinely still a tool most radeon users i know who game alot, keep installed.. wish the creator would either come back or release his source so users could update and expand it... and make it work on nvidia as well as amd hardware... (mostly because, it can inject smaa in a way games dont view as possible cheating, where, the same games often view using sweetfx/reshade to do the same as possible cheating... stupid... specially for games where..anything it could inject would be... pointless... aimbots arent really a thing in mmos that lack headshot/etc mechanics..... bots arent too rare...farm bots are...allover... but they dont tend to do more then run around collecting ♥♥♥♥.. so..yeah...not something thats "oh god, they killed me again"

sounds like nvidia and amd are planning to stop adding new profiles next year (nv announced it but amd also have been treating cf like the bastard step child for a while now...) and since dx12/vulkan need the support baked into the game... good excuse to shift the responsibility to devs and pretend they are helping every dev the best they can..
