is anyone else running an Intel Arc B580 graphics card and noticed terrible performance?
i recently upgraded my Zwift system and it is struggling to do 30- 40fps at even 1080p. This is after 2x clean reinstalls of windows and Zwift with latest drivers etc
Can confirm the B580 runs all other benchmarks and games 100%, only outlier is Zwift. At the moment it runs worse than the intel integrated graphics on my 8th gen NUC mini pc.
This card should be capable of 60~90fps on 4k ultra atleast.
What CPU do you have? Can you upload your logs to zwiftalizer.com and share the results here?
I have a Ryzen 7 7700 with each of the 8 cores/16 threads boosting to over 5.4ghz during the Zwift session so there is no shortage of cpu power.
Will run a session this evening and upload the log.
I did check Zwiftalizer for comparable results but there is nothing with the B580 recorded yet. The previous intel card that this one replaced (A770) has logs of 60fps+ in 4K ultra and the B580 is supposed to be the faster model of the two.
Support for the B580 was added in 1.89. Do you get Ultra albeit very slow ?
i’ll check if it is defaulting to ultra or basic when i upload the log
i can confirm that there is barely 5~10fps difference between 1080p and 4k in the current quality mode though
even if it were running in basic i would expect 100+ fps surely. Even my old 2gb GTX1050 is 2~3 times faster at the moment
Doesn’t sound good. Video Screenshots feature turned off? That costs a few FPS, not the whole difference to a reasonable frame rate though. Running this driver from a few days ago? https://www.intel.com/content/www/us/en/download/785597/intel-arc-iris-xe-graphics-windows.html
was a default installation so if video screenshots is enabled by default then it is probably still enabled. As you said, might be a frame or 2 but wouldn’t account for the rest.
Correct, running the latest Intel driver as of yesterday (actually tried the WHQL and the latest non-WHQL driver, same result)
Video Screenshots should be on by default on the 7700 and I would definitely turn it off and see what happens. It’s quite possible this card won’t work well as things stand. I’d be interested to see your results from zwiftalizer.com. The A770 looks pretty respectable when I search Zwiftalizer for previous uploads.
Hi @Gavin_Sheehan welcome to Zwift forums.
Shuji at Zwift HQ here. I took the liberty of uploading your server log file to Zwiftalizer.com.
This is a third party tool that analyzes your game logs to see what’s happening on your end.
This is Zwiftalizer’s parse of your May 28 log.
I can confirm that the Arc B580 GPU does support Ultra profile. What the logs don’t tell us is information about how your external monitor(s) are set up (i.e. how many, the Windows resolution settings of those monitors, the native resolution the monitor(s) are capable of, the type and length of video cable you’re using, if that monitor is daisy-chained through another monitor, USB-C hub, KVM switch, etc)? Did any of those variables change vs your previous GPU?
thanks for sharing!
i joined zwiftalizer and just did another test at 1080p now. connected to a 65" 4k TV 60hz with V-Sync disabled. Connected directly via 1m hdmi cable. Only ran these tests for a few mins so the average fps is skewed quite heavily by the menu at the start and the menu at exit that are high fps. In game i dont see much more than 25 to 35fps using a frame rate counter
@zwiftalizer I’m wondering why “B580” gets no results when searching Zwiftalizer. Any ideas?
i just noticed that now as well, though there would be atleast one after my upload now
i appreciate the assistance guys, would be a pity to swap with another card to get playable again
what is interesting is the card barely draws more than 40w of power in game, when it renders the menus at the start and end it ramps up to over 100w (frames jump up to 300+).
when in game there also seems to be jitter to the screen, like its shaking slightly every now and again
maybe this card is just incompatible in its current driver and zwift version state
That makes it sound CPU limited for some reason, which can be related to the GPU/driver. Perhaps you can identify a CPU core that is 100% busy while you are riding? Most of the cores will be unused but that’s normal for Zwift.
yes i have msi afterburner running and it always shows atleast 2 cores running at full boost speed (5.45ghz)
Hello Paul, the B580 isn’t in the search results yet because I rebuild the search index every couple of months or so to save on costs. Also, I only include results for activities longer than 5 minutes. I’ll run the indexer later today.
I only ran the tests for a few mins for testing purposes hence the short durations. The in-game performance is unfortunately not pleasant enough to do an actual ride.
Looking forward to seeing a few other results from other users to compare against though. Will swap back to my previous graphics card for now so that i can ride again and test this again in the future (hopefully by then something has changed and compatibility is better)
Could run the game in Just Watch mode for 5 min but DO NOT LOOK and get the data for science 
Thank you for refreshing
very interesting, looks like one other person was just testing for a few mins, the big numbers are in menus i assume with a massively low p1 fps of only 13
The other had to drop to 720p on basic to get a playable ride (on a very fast cpu)
Those were on 1.87 and 1.88 so would only get basic at best.
