Really poor performance on 5.6 android

Hi i have a two game made with 5.4 and 5.6

first game made with 5.4 and average stats values are like 120k tris, 130 setPass and 3ms cpu usage. game is really smooth and do not have any trouble on any device.

But second game made with 5.6 and average stats value like 50k tris, 50setpass and 2.5ms and lagging like a hell. I tried Opengl 3, 2 and vulkan api’s but nothing changed.

Is there any one one what changed in 5.6 and killed performance? I trusted unity’s vulkan teasing video and it failed my game playing by millions player. what should i do now?

Any help will makes me glad.

@akguldeniz Did you get anywhere with this? I’m seeing a similar drop in performance on 5.6.
