I also checked with GTA IV game -- with the new thermald performance also decreased. Average FPS for in-game benchmark drop from 53 to 42 (I run only one attempt for each thermald version) (and game became unplayable as minimum FPS in complex scenes became less than 30). GTA IV has a different CPU load pattern: while STALKER loads only one CPU core but to 100%, GTA IV looks to be multi-threaded -- it utilizes all cores but all of them partially (no one was > 50%).

It became impossible to play video games on the laptop. System: Ubuntu 20.04.3 LTS Kernel: 5.10.0-1045-oem Laptop: Dell XPS 9310, CPU: Intel Core i7-1165G7 (Tigerlake), Integrated GPU Iris Xe. BIOS 2.1.1 03/25/2021 Display: 2560x1440 144Hz HDMI USB-C connection Room temperature is 23.5-25.4 degrees Game: Stalker Clear Sky (Wine/Proton Steam) Note: The game itself is very old and loads 100% of one CPU core disregarding of frequency. GPU frequency is monitored by intel-gpu-top GPU frequencies (according to /sys/class/drm/card0/) min/max/boost/efficiency: 100/1300/1300/400 Previous behavior (1.9.1-1ubuntu0.4) After starting the game at first GPU reaches the boost value of 1300 MHz and CPU/package temperatures continuously increase. At this point game renders at ~80FPS. After some time when threshold temperature value (~78 degrees) is reached the GPU frequency decreases to ~660 MHz and FPS to 40-48 FPS. Package temperature decreases to 66-68 degrees. It's possible to play for indefinite amount of time. New behavior (1.9.1-1ubuntu0.4) After starting the game at first GPU reaches the boost value of 1300 MHz and CPU/package temperatures continuously increase. At this point game renders at ~80FPS. But after reaching the threshold temperature (about 81 degrees) GPU frequency decreases to 400 MHz (gt_RP1_freq_mhz -- "efficiency" temperature for the GPU) and stays on this value for the indefinite amount of time. The temperature is maintained on 70-74 degrees. FPS is about 25-30 FPS, it is not possible to play the game anymore. The only way to return the good FPS and frequency is to fold the game window, wait some time and open it again. Also there is a workaround -- limit the CPU frequency to 2001 MHz and disable Intel turbo boost. With such approach package temperature never reaches 80 degrees and it is possible to play game with 500 MHz and 35-40 FPS. Better than nothing. If it is needed I can perform any additional checks, provide CPU frequencies and so on. Most probably regression happened with 1.9.1-1ubuntu0.5, but I tried only versions 0.4 and 0.6 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/thermald/+bug/1944389/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
