Menu is stuttering, hovering between 20-40 FPS. When in game, FPS seems stable around 120-160 but gameplay is very sluggish. It seems every couple of seconds the framerate drops completely, resulting in a very choppy gameplay experience. Since today, after a few minutes of playing the framerate drops to around 20 FPS and the only way to fix it, is to restart the game.\r\n\r\nI'm running Ubuntu 14.04 with an Intel 2500K CPU and a Nvidia 560Ti GPU with the 343.22 drivers.\r\n\r\n\r\nSystem information:\r\n\r\nProcessor Information:\r\n    Vendor:  GenuineIntel\r\n    CPU Family:  0x6\r\n    CPU Model:  0x2a\r\n    CPU Stepping:  0x7\r\n    CPU Type:  0x0\r\n    Speed:  3601 Mhz\r\n    4 logical processors\r\n    4 physical processors\r\n    HyperThreading:  Unsupported\r\n    FCMOV:  Supported\r\n    SSE2:  Supported\r\n    SSE3:  Supported\r\n    SSSE3:  Supported\r\n    SSE4a:  Unsupported\r\n    SSE41:  Supported\r\n    SSE42:  Supported\r\n    \r\nNetwork Information:\r\n    Network Speed:  \r\n    \r\nOperating System Version:\r\n    Ubuntu 14.04.1 LTS (64 bit)\r\n    Kernel Name:  Linux\r\n    Kernel Version:  3.13.0-36-generic\r\n    X Server Vendor:  The X.Org Foundation\r\n    X Server Release:  11501000\r\n    X Window Manager:  Compiz\r\n    Steam Runtime Version:  steam-runtime-release_2014-08-20\r\n    \r\nVideo Card:\r\n    Driver:  NVIDIA Corporation GeForce GTX 560 Ti/PCIe/SSE2\r\n\r\n    Driver Version:  4.4.0 NVIDIA 343.22\r\n    OpenGL Version: 4.4\r\n    Desktop Color Depth: 24 bits per pixel\r\n    Monitor Refresh Rate: 60 Hz\r\n    VendorID:  0x10de\r\n    DeviceID:  0x1200\r\n    Number of Monitors:  2\r\n    Number of Logical Video Cards:  1\r\n    Primary Display Resolution:  1920 x 1080\r\n    Desktop Resolution: 3840 x 1080\r\n    Primary Display Size: 20.51\" x 11.54\"  (23.50\" diag)\r\n                                            52.1cm x 29.3cm  (59.7cm diag)\r\n    Primary Bus: PCI Express 16x\r\n    Primary VRAM: 1024 MB\r\n    Supported MSAA Modes:  2x 4x 8x 16x \r\n    \r\nSound card:\r\n    Audio device: Realtek ALC889\r\n    \r\nMemory:\r\n    RAM:  7968 Mb\r\n    \r\nMiscellaneous:\r\n    UI Language:  English\r\n    LANG:  en_AU.UTF-8\r\n    Microphone:  Not set\r\n    Total Hard Disk Space Available:  1862285 Mb\r\n    Largest Free Hard Disk Block:  1730242 Mb\r\n    \r\nInstalled software:\r\n    \r\nRecent Failure Reports:\r\n    \r\n"},"comment":{"url":"https://api.github.com/repos/ValveSoftware/Counter-Strike-Global-Offensive/issues/comments/77260412","html_url":"https://github.com/ValveSoftware/Counter-Strike-Global-Offensive/issues/141#issuecomment-77260412","issue_url":"https://api.github.com/repos/ValveSoftware/Counter-Strike-Global-Offensive/issues/141","id":77260412,"user":{"login":"d2kx","id":4834966,"avatar_url":"https://avatars.githubusercontent.com/u/4834966?v=3","gravatar_id":"","url":"https://api.github.com/users/d2kx","html_url":"https://github.com/d2kx","followers_url":"https://api.github.com/users/d2kx/followers","following_url":"https://api.github.com/users/d2kx/following{/other_user}","gists_url":"https://api.github.com/users/d2kx/gists{/gist_id}","starred_url":"https://api.github.com/users/d2kx/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/d2kx/subscriptions","organizations_url":"https://api.github.com/users/d2kx/orgs","repos_url":"https://api.github.com/users/d2kx/repos","events_url":"https://api.github.com/users/d2kx/events{/privacy}","received_events_url":"https://api.github.com/users/d2kx/received_events","type":"User","site_admin":false},"created_at":"2015-03-04T22:06:56Z","updated_at":"2015-03-04T22:06:56Z","body":"Just to update. The weird stutters are gone now. There are still stutters if you are playing for the first time, at least with AMD Catalyst, but that is expected behaviour because the shaders are compiled once and written into the shader cache. After that, it's smooth now."}}
