I have been facing the same problem, for a year now. The last usable version for me is 1.5.2, sadly. Anything above lags like hell on every phone I have, even on not-so-old Motorola OneVision. It looks like many phones cannot cope with SharedMemoryPlugin introduced in v1.6 even after lowering down the refresh rates. I got so hyped when I saw people reporting running ACC-CDS in browser on the PC in the background (parallel to app/browser on the phone) fixed this issue but nope - not for me.Im having huge issues with lag with the dash, when i rev the engine, the revs almost is in sync, but gears, laptimer and everything else has a huge delay, is there anything i can do on my end? My other dashes works just fine.
Even when I am in the pits, the moment I rev higher than 4500 lagging starts and if I floor it it lags even worse and when I start driving it's a slideshow with 3+ seconds lag. I would love to use v2 mainly for the 2nd display improved since v1.5 because in Audi (and many other cars I think) the Racelogic and/or Lumirank 'hide' behind bezels in triple-screen setups. I tried overlaying both acc-cds dashes and 2nd display in windowed mode, above ACC, and it worked in sync but conflicted with Gsync so even with FPS remaining the same the gameplay was not as fluent. WiFi 5GHz, port forwarding, setting priorities in the router, no firewall, even USB tethering did not help with the phone. Surprisingly the 2nd screen works perfectly fine, it's only the main CDS that lags. All other dashes work fine as well. Such a pity as Ensi's work is way above any standard
Anyone using Vocore has issues with lags or does it cope with ACC-CDS very well? If it works then I think I know what needs to be bought...
