--- Comment #24 from Kai <k...@dev.carbon-project.org> --- I've made some screenshots with the Pre-Sequel as well: <https://imgur.com/a/DnoC1>. As you can see, big FPS drops coincide usually with buffer wait time and/or draw call spikes. Some of these spikes can be correlated to "stuff happening on the screen", but in other cases drops can come out of nowhere, so to speak. With VBlank on, FPS capping at 60 FPS, all video settings to max, a 2560×1440 resolution, CPUfreq governor set to performance (really helps reducing the frequency of the FPS drops/buffer wait time spikes) and the stack detailed below, I get 40 to 60 FPS most of the time. The images show the "error" case. My current stack is (Debian testing as a base): GPU: Hawaii PRO [Radeon R9 290] (ChipID = 0x67b1) Mesa: Git:master/2883aff3be libdrm: Git:master/00847fa48b LLVM: SVN:trunk/r219920 (3.6 devel) X.Org: 2:1.16.1-1 Linux: Git:~agd5f/linux:drm-next-3.18:369283bfbd + attachment 107451 and attachment 107544 (identifies itself as 3.17.0-rc5) Firmware: <http://people.freedesktop.org/~agd5f/radeon_ucode/> > 9e05820da42549ce9c89d147cf1f8e19 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_ce.bin > c8bab593090fc54f239c8d7596c8d846 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_mc.bin > 3618dbb955d8a84970e262bb2e6d2a16 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_me.bin > c000b0fc9ff6582145f66504b0ec9597 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_mec.bin > 0643ad24b3beff2214cce533e094c1b7 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_pfp.bin > ba6054b7d78184a74602fd81607e1386 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_rlc.bin > 11288f635737331b69de9ee82fe04898 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_sdma.bin > 284429675a5560e0fad42aa982965fc2 > /lib/firmware/updates/3.17.0-citadel/radeon/hawaii_smc.bin libclc: Git:master/7f6f5bff1f DDX: 1:7.5.0-1 -- You are receiving this mail because: You are the assignee for the bug.
