Exclamation [Q] Enabling ART causes Nexus 7 to lag

I am using Slimkat ROM build 4997 with F2FS on my Nexus 7 Grouper

Enabling ART on this device seems to cause major lag and slowdowns. Can anyone help on why this is happening? I was expecting faster performance compared to Dalvik.

ART is still hit and miss because not all apps are compatible with it, yet. I have a simple setup with my N7 and ART runs just fine. I'm not running Slimkat at this time, however.
Nexus 4 -- PLSX or OmniROM; Nexus 7 3G -- OmniROM; Asus TFP -- CM10.1; Kindle Fire -- CM11

Did u try some other rom? Im using liquidsmooth with art and it is seriously fast. Btw, ART basically reduces app loading times not much else. Try overclocking if u want a serious improvement in performance

I would not overclock the N7. There is a big battery drain even without OC. And the speed improvement isn't that much. For me ART needed it's time establish and then it ran smooth.

I was just looking for this topic myself. Same.. I'm running AOKP 4.4.4 on f2fs.. We all know the N7 2012 is a lag monster but I figured ART wouldn't hurt, but in reality I'm seeing slower launches, in-app lags, just random stutters in apps that I've never seen before.

I'm going back to Dalvik, looks like it's not just me. Maybe ART wasn't on this chipset for a reason (not optimized for Tegra 3 etc).
AT&T LG G2 - 4.4.4, AOKP
Nexus 7 Wifi 2012 - 4.4.4, AOKP (m-kernel)
Samsung Note i717 - 4.2.2, Unofficial AOKP
