Build 174448 for Serious Sam 3 is released.
If you have previously opted into public beta, you already have this. For all others, here is the list of changes:

- Linux: Added log messages for connected gamepads.
- Linux: Added inp_bLogGamepadEvents cvar for logging gamepad events.
- Linux: Fixed crashes on some window managers due to missing Xlib atoms.
- Added support for OpenGL tearing in VSync via 'ogl_bVSyncTearing' cvar. When cvar is on, screen refresh will wait for number of retraces specified via 'gfx_iWaitVSyncs' cvar and if more vertical retraces passed, will not wait for next one, but will do swap as soon as possible.
- Fixed wrong report of utilized OpenGL extensions.
- Slider widgets in color options menu are now enabled/disabled depending on support of gamma-correction also, not only full-screen or window mode.
- Fixed resolution downsizing not downsizing some buffer in-game causing more GPU memory usage than needed.
- Fixed command bindings not displaying properly in spectator view HUD.
- Added news feed to start screen.
- Editor: Fixed crash when exporting textures.
- Editor: Khnum and Aircraft puppets no longer ignore lethal damage. This allows Killer entity as well as macro functions such as DropDead() to affect these puppets.
- Editor: Added a new macro function to base entity: InflictWeaponDamage(). This function deals damage equivalent to one produced by any given weapon.

Build 173936 for Serious Sam 3 is released.

- Linux: Various fixes for visual artefacts caused by GPU resource corruptions that happened when game was minimized, alt-tabbed or otherwise lost focus.
- Faster switching into game after Alt-Tab, and changing Gfx APIs.
- Linux: Outdated driver versions are now reported to user on Linux.
- Linux: Fixed zombie processes sometimes being left over by the game.
- Fixed problem where correct video mode wasn't started when changing back to game (via alt-tab) if cvar 'gfx_iAPI' is set to gfx API that is not actually supported by the platform.
- Added CPU name detection and output to console.
- For detecting GPU vendor and device ID under Linux, "lspci" external command is now used instead of "libpci" interface.
- OSX: Some fixes for handling of gained/lost keyboard focus.
- Prevented possible application crash that may occur during Steam Workshop sync IO failure.
- Handling of GPU synchronization (if gfx_iFinish>0) is now more responsive. It would sometimes cause stuttering previously.
- FPS counter variation is now also displayed (minimum and maximum frame rate for last refresh interval). Controlled via 'prf_bShowFPSVariation' cvar. (Default is on.)
- Fixed crash at start if Steam is running in offline mode.
- Mouse is no longer confined to window after alt-enter.

Build 173456 for Serious Sam 3 is released.

If you have previously opted into public beta, you already have this. For all others, here is the list of changes:

Update 173456 contains a number of general fixes in the game, as well as some that are specific to the Linux version.

- IMPORTANT FOR LINUX: Most of the weird performance problems in previous builds were caused by performance throttling (aka power saving) features on various CPUs not correctly identifying that the game is running and continually jittering between low and high performance modes (several times per second sometimes!). This build adds a workaround for this which should hopefully prevent the symptoms from being so extreme. It is not perfect however, as there might still be a few percents of performance to squeeze out. The recommended solution is to turn off such features in BIOS for Linux machines. They can be found in BIOS under names such as SpeedStep, Cool'N'Quiet, C1E, PowerNow!, Power Saving, CPU Throttling, Dynamic Frequency Scaling, or something else - depending on your BIOS.

- Added a script that offers to automatically install libpci.3 on linux if it is missing.
- Fixed graphics corruption under OpenGL if game is minimized or "alt-tabbed" while it is loading content.
- Fixed screen-shot grabbing and manual save-game thumbnails not working under OpenGL.
- OpenGL library can now load even if some vendor dependent functions are missing.
- X11 libraries on Linux are now dynamically loaded, so game can properly report and error if something is missing.
- Dedicated server on Linux no longer requires X11 to be installed.
- Fixed problems with filenames of wrong case that happened only with Linux dedicated server.
- Full support for language packs in Workshop. Language mods can now work even in pure (non-moddable) version of the game, and don't require any customization from user side. Just subscribe to them.
- Workshop packages menu is now also available in non-moddable version of application (this allows enabling/disabling of language packs).
- User is now properly notified when Steam Workshop content download fails.
- Fixed issues that might have prevented some user accounts from uploading to Workshop.
- SeriousEditor now displays Steam Workshop sync progress in status bar.
- Upload to Steam Workshop command is no longer available until Steam Workshop sync is finished. Previuously, it locked up the application.
- Fixed an issue causing clients to always see weapon change on HUD at game start.
- Fixed a lockup happening if spectator cameras are linked in a closed loop. This only happened with user-made levels.
- Weapon change attempt is now correctly being indicated on HUD if performed during sprint.
- Fixed popup menus in Serious Editor sometimes going off the bottom of the screen in multimonitor setups.
