Raw Normal View History

small vulkan perf tweak. fix capturedemo over vid reloads. fix playfilm letterboxing issue. con_printf will now create consoles as needed. fix .skin compose line. fix a couple of q3bsp issues core gl contexts will no longer be given pre-core glsl shaders, is the theory. qcc now warns about unused fields. use the __used keyword to mark those fields as actually needed. use __unused to allow the qcc to potentially silently strip them. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5166 fc73d0e0-1445-4013-8a0c-d673dee63da5

!!ver 100-450
changed to not load gamecode from quake paths, to avoid issues with buggy quakeworld clients that will freely download stuff from anywhere (not sure what to do about ktx, but it can be reenabled with a cvar). image_width is now only set by a single function. tweaked scancode inputs slightly. added support for printscreen binds. changed the way gamma works. glsl gamma now used when running windows, or hardware gamma is not available. removed gl_contrast+gl_brightness. q2 gamecode support no longer has a system componant. this means that ports only need the generic stuff. misc tweaks to the d3d11 renderer. added brief descriptions to many builtins. need to add comments to constants, globals, and fields too, somehow. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4355 fc73d0e0-1445-4013-8a0c-d673dee63da5

added cmake file. reduced input latency. reworked how internal texture formats work,. added support for LIGHTING_E5BGR9 bspx lump for HDR lighting. updated support for srgb, no longer looks quite so weird. works on glx vid_srgb 3 attempts to use half-float swapchains, where possible. gl: use glTextureStorage where available. d3d11: gave up on using dxgi for fullscreen, was just too buggy. glx: updated gl context creation on linux. server: fix svc_updatefrags not being passed though (fixes frikbot scores) fs: spanned pk3s now work (fragmented files/directory will fail to open, so this needs a custom tool to be fully useful). fixed restart_ents command (restarts the map, but preserving the players as they are) tw: removed 'QWSKINS' featureset from tw config git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@5217 fc73d0e0-1445-4013-8a0c-d673dee63da5
