Это описание возможностей каждой версии DirectX в качестве справочного материала для созданиия резервной поддержки старых графических процессоров с более низким уровнем функциональности DirectX. В каждом разделе указаны возможности не поддерживаемые в предыдущих версиях DirectX | |||
{{ | Для проверки более низние уровни функциональности DirectX на передовых графических картах, используйте [[CVAR|CVAR]] [[mat_dxlevel]]. Установите CVAR в 60, 70, 80, 81, 90, 95 или 98 ({{360}}) для установки соответствующей версии DirectX. Не возможно использовать версию DirectX выше, чем доступно графическому оборудованию. | ||
{{ModernImportant|Please note that this has ''nothing to do with'' changing the '''Direct3D''' renderer ('''D3D''' for short, incorrectly refers to ''DirectX renderer'') to use Direct3D 8 or older. Source will always run on '''Direct3D 9''' (or '''Direct3D 11/12''' on [[Titanfall_engine_branch|some]] [[Strata_Source|third-party]] branches). However, the materials, effects and shaders will be changed or disabled for compatibility with older GPUs that predates Direct3D 9, or to allow modern tools such as {{nvidia|4}}'s {{rr|4}} (also used in {{portalrtx|2}} and upcoming {{hl2rtx|2}}), which currently only support DX9 (D3D9) or earlier (with compatibility level 8.x or lower, or with fixed function pipelines), to work properly.}} | |||
{{note|Source games and engine branches released by Valve since {{l4d|4}} no longer support DirectX compatibility levels below DirectX 9, aswell replaced the old DirectX compatibility level with new shader & effect details option. The only modern Source engine branch that still supports older DirectX versions (down to 8.0) is {{src13|4}}. Some third-party Source engine branch or Source successor, {{source2|1}}, will only support DirectX 11 (including the Direct3D renderer) or later.}} | |||
{{note|On most modern PCs with modern GPUs, these always run with DX11 or newer (and fully support all DX9 features in Source). Players running on DX8 level cards or older on systems with [[Steam]] are [https://store.steampowered.com/hwsurvey/directx/ non-existent] (according to Steam Survey). Make alternate assets if you want, but almost no one will see them unless they launched the game with -dxlevel 80/81 manually or have a very old system, or by launching a game that utilizes {{Nvidia|2}} {{rr|2}}, which was only used in {{Portalrtx|4}} and {{hl2rtx|4}}, used to convert most of the DX8 level graphics, or by triggering a bug that {{src13|4}} commonly had which only occurs on some modern systems.}} | |||
{{Bug|only=src13|On some modern systems, when a {{src13|4}} game is run for the first time, the game may default to DirectX 8 materials.<br>To fix this, run the game once with {{code|-dxlevel 95}} command line option, change your video settings, then save by clicking OK (or Apply then OK), then close the game, open it again, it should show as Software DirectX level: '''DirectX 9.0+''' on the video options.}} | |||
{{Bug|Some effects appears to be missing (or barely visible), such as {{Code|[[func_illusionary]]}} used for fake [[volumetric lighting]], or the game looks more desaturated compared to DirectX 8 mode.{{Cite|1}}{{Cite|2}} See [[#Train Station]]}} | |||

In {{Portalrtx|4}} and in other RTX Remix Source games, the game will run on DirectX 7 or 8 mode in order to make {{rr|4}} work. Also, when using Vulkan renderer on non-RTX Remix games, using {{code|dxlevel}} lower than 90, such as 80/81 for DirectX 8 will cause the game to not render properly. | |||

Revision as of 23:49, 8 June 2024
Это описание возможностей каждой версии DirectX в качестве справочного материала для созданиия резервной поддержки старых графических процессоров с более низким уровнем функциональности DirectX. В каждом разделе указаны возможности не поддерживаемые в предыдущих версиях DirectX
Для проверки более низние уровни функциональности DirectX на передовых графических картах, используйте CVAR mat_dxlevel. Установите CVAR в 60, 70, 80, 81, 90, 95 или 98 (
) для установки соответствующей версии DirectX. Не возможно использовать версию DirectX выше, чем доступно графическому оборудованию.
Важно:Please note that this has nothing to do with changing the Direct3D renderer (D3D for short, incorrectly refers to DirectX renderer) to use Direct3D 8 or older. Source will always run on Direct3D 9 (or Direct3D 11/12 on some third-party branches). However, the materials, effects and shaders will be changed or disabled for compatibility with older GPUs that predates Direct3D 9, or to allow modern tools such as 
Nvidia's 
RTX Remix (also used in 
Portal with RTX and upcoming 
Half-Life 2 RTX), which currently only support DX9 (D3D9) or earlier (with compatibility level 8.x or lower, or with fixed function pipelines), to work properly.
Примечание:Source games and engine branches released by Valve since 
Left 4 Dead no longer support DirectX compatibility levels below DirectX 9, aswell replaced the old DirectX compatibility level with new shader & effect details option. The only modern Source engine branch that still supports older DirectX versions (down to 8.0) is 
Source 2013. Some third-party Source engine branch or Source successor, Source 2, will only support DirectX 11 (including the Direct3D renderer) or later.Примечание:On most modern PCs with modern GPUs, these always run with DX11 or newer (and fully support all DX9 features in Source). Players running on DX8 level cards or older on systems with Steam are non-existent (according to Steam Survey). Make alternate assets if you want, but almost no one will see them unless they launched the game with -dxlevel 80/81 manually or have a very old system, or by launching a game that utilizes Nvidia RTX Remix, which was only used in Portal with RTX and Half-Life 2 RTX, used to convert most of the DX8 level graphics, or by triggering a bug that Source 2013 commonly had which only occurs on some modern systems.
Баг:On some modern systems, when a Source 2013 game is run for the first time, the game may default to DirectX 8 materials.To fix this, run the game once with -dxlevel 95 command line option, change your video settings, then save by clicking OK (or Apply then OK), then close the game, open it again, it should show as Software DirectX level: DirectX 9.0+ on the video options. [нужно проверить в ?]
Баг:Some effects appears to be missing (or barely visible), such as func_illusionary used for fake volumetric lighting, or the game looks more desaturated compared to DirectX 8 mode.[1][2] See #Train Station [нужно проверить в ?]Возможности DirectX
Предупреждение:Since 
Source 2006, DirectX 6 is no longer supported.
Since 
Source 2007 or 
Source 2009, DirectX 7 is no longer supported.
Starting with Версия платформы Left 4 Dead and later Source games, all DirectX 8 versions are no longer supported.
In Portal with RTX and in other RTX Remix Source games, the game will run on DirectX 7 or 8 mode in order to make RTX Remix work. Also, when using Vulkan renderer on non-RTX Remix games, using dxlevel lower than 90, such as 80/81 for DirectX 8 will cause the game to not render properly.

"dxlevel 92"
This is equivalent to dxlevel 95, but use the translator ToGL to convert the DirectX calls to OpenGL calls. Only on 
macOS and 
Linux, and other platforms/operating systems that do not support Direct3D and DirectX.
DirectX 9 / D3D9.0c - Shader Model 3 (Во всех играх начиная с Source 2006)
Referred to as "DirectX 9.0+" and "dxlevel 95". Last version supported for all version of Windows 98/98SE/ME/2000 and XP. Older Source 2 games like 
Dota 2 previously supported Direct3D 9, before it was dropped in 2021.
Features
- Lightwarp support
- High dynamic range rendering (enabled by default)
DX9Ex
Referred to as "dxlevel 98". Made specifically for Xbox 360.
Предупреждение:Doesn't work or doesn't do anything much in PC builds of any game (the game will reset to dxlevel 95 after changing video settings). Only works for Xbox 360, where it is required.
Подтвердить:
Counter-Strike: Global Offensive also use DX9Ex, but it is unknown which "dxlevel" this game is currently using. DX9Ex in CS:GO is not the same as the one used in Xbox 360 Source games.Features
