Hey guys. I really need your help. I don´t know, if something similar happened to you, but this is serious stuff. Not only serious. It´s "Iabsolutelyhavenoideawhatcanpossiblybewrong" stuff. I recently bought my beautiful new One. It came with CM11S 44S installed on it. The device was so fast, that even running Duke Nukem 3D on computer with Intel Core i7-5960X Extreme Edition, 32GB RAM and 2 nVidia GeForce 980 in SLI seemed like watching snail mixed with turtle running for its life. I used INTERACTIVE governor all along. But one day I decided to flash Vanir ROM in my One. Everything went fine. I used it for a while, but then decided to get ready for upcoming CM12S OTA and I went back to stock CM11S 44S. I downloaded official signed bacon image and did a full stock rollback. I did full cache wipe, dalvik cache wipe, full system and data wipe, literally fullest wipe a regular human being can possibly do. The phone was cleaner than a pair of underpants just pulled out of the washing machine. It was empty. Then I flashed that official stock image, stock recovery, stock everything. The phone was like it was just assembled in a OPO factory. It turned on, I set up everything back to normal, logged in my google account, gathered my backup and contacts. But since then, my OPO is laggy. Really. No kidding. INTERACTIVE governor is laggy in games, where it was never laggy before. I am not talking about Modern Combat 5 with ultra details and 10K resolution or some other extreme stuff. I am talking about Fun Run, Dumb Ways To Die. About these kind of games. So. My question. How is this possible? Everything was fine before flashing. Is it possible (just thinking out loud), that with the flashing I reformatted something? Or damaged some partition? Or something? I don´t know. Am I the only one here with this problem? I made absolute clean install on an empty wiped phone. Official image. Stock recovery. Everything back like it is supposed to be. 44S. INTERACTIVE governor. But it lags. I even tried to change governor to CONSERVATIVE. CONSERVATIVE was fine. But I don´t understand. Before flashing, INTERACTIVE went absolutely amazing. And there is no way, that CONSERVATIVE can be faster and smoother than INTERACTIVE. CONSERVATIVE is more lazy. Please. Help.
