Familiarize yourself with the following terms used by GSdx: | Familiarize yourself with the following terms used by GSdx: | ||
* '''Renderer''' -- A choice between, DirectX 11 and OpenGL. There are two subtypes for each API: | * '''Renderer''' -- A choice between, DirectX 11 and OpenGL. There are two subtypes for each API: | ||
** '''Hardware renderer''' -- | ** '''Hardware renderer''' -- Uses your graphics card to render the picture. This is the fastest and preferred mode. | ||
** '''Software renderer''' -- | ** '''Software renderer''' -- Uses your CPU to render the picture. There will be ONLY native internal resolution available (thus original PS2 visuals). In some cases this mode may produce the best images with the least amount of graphical artifacts. Unfortunately GSdx requires quite a bit of CPU power to render with the software renderer even in internal resolution (without anti-aliasing or anything else applied) so you may end up with a correctly rendered game but which only runs at an unplayable 3-10 fps. Note also that PCSX2 is very CPU hungry but currently supports only 2 cores (the third core may also help a wee when used by different system processes leaving first two exclusively to PCSX2) thus if you have a 3+ core CPU you may consider using them for GSdx working in this mode increasing the render speed dramatically with every additional core (see '''SW renderer threads'''). You can also switch between hardware renderer and software renderer during runtime, see [[GSdx#List_of_ingame_keys|'''List of ingame keys'''-'''F9''']]. | ||
* '''Adapter''' -- Specifies which of the available adapters to use when using Direct3D API. | |||
* '''Interlacing (F5)''' -- Is used to choose the default deinterlacing mode when starting the emulation process. For more detailed explanation see [[GSdx#List_of_ingame_keys|'''List of ingame keys'''-'''F5''']]. | |||
* '''Texture Filtering''' -- Default option: PS2. The nearest option will look blocky but is the fastest. The PS2 option will make GSdx only apply filtering to textures when the game's code calls for it, just like the PS2. The forced option will filter ALL textures (reducing shimmering) but may also cause texture glitches. | |||
===Hardware Mode Options=== | |||
* '''Allow 8-Bit Textures''' -- When checked 4/8 bits texture will be send to the GPU with a palette. GPU will be in charge of the conversion. When unchecked the CPU will convert directly the texture to 32 bits.It is basically a trade-off between GPU/CPU. | |||
* '''Large Framebuffer''' -- Allocate a large framebuffer to be compliant with GS memory (Prevents FMV flickering when upscaling). It increases GPU/memory requirements. It should be disabled for Armored Core, Destroy All Humans, and Gran Turismo as it will amplify VRAM usage by a lot. | |||
* '''Internal Resolution''' -- Is used to set the render resolution target. The higher resolution you choose here the bigger picture will be rendered before being resized into your screen resolution thus you'll see more clear and crisp visuals. Unfortunately all those game you'll be playing were created and tested for lower native resolution (~500 x ~450) so some picture parts or objects may look wrong (displaced/framed/no image/invalid colors, etc.) when rendered in higher resolution. These artifacts you may eliminate only by using '''native resolution'''. Increasing internal resolution will impact the rendering speed so the higher resolution you set the more powerful graphics card you'll need to have. | |||
* '''Custom Resolution''' -- Not recommended. It is used to set custom resolution for the rendering target, will cause issues and many features do not work properly with it. It is better to use the resolution multipliers instead. | |||
* '''Anisotropic Filtering''' -- Reduces texture aliasing at extreme viewing angles. Automatic option is recommended. | |||
* '''Mipmapping (Ins)''' -- Control the accuracy level of the mipmapping emulation. Automatic option is recommended. | |||
* '''CRC Hack Level''' -- Control the number of Auto-CRC fixes and hacks applied to games. | |||
* '''DATE Accuracy''' -- Implement a more accurate algorithm to compute GS destination alpha testing. It improves shadow and transparency rendering. | |||
* '''Blending Accuracy''' -- Control the accuracy level of the GS blending unit emulation. | |||
* '''Enable HW Hacks''' -- Enables the use of HW Hacks which can be toggled in Advanced Settings and Hacks. | |||
===Software Mode Options=== | ===Software Mode Options=== | ||
* '''Auto Flush''' -- Force a primitive flush when a framebuffer is also an input texture. Fixes some processing effects such as the shadows in the Jak series and radiosity in GTA:SA. | |||
* '''Mipmapping''' -- Enables mipmapping, which some games require to render correctly. | |||
* '''Edge anti-aliasing (Del)''' -- A feature of the actual GS on the PS2. It can only be used in software renderer modes. This can improve the resulting visuals (provided that the game supports it and is calling for it to be applied on the current scene) by applying an anti-aliasing algorithm. It will cause a very minor performance drop. This feature is required to emulate some games. | |||
* '''Rendering threads''' -- chooses the number of threads (pipes) to render the picture in software mode. Every additional thread here means one additional CPU core will be used in the rendering process. You're still going to need at least one core left for the PCSX2 itself so if you, for instance, have 4 cores (quad core CPU) you may want to set this field to 3. | |||

* ''' | * '''Rendering Hacks''' | ||
* ''' | ** '''Alpha Stencil''' -- Improves shadows/transparency rendering in games such as Amagami. It will break transparency rendering in many games, avoid using it. DATE Accuracy does the same job accurately. | ||
* ''' | ** '''Auto Flush''' -- Force a primitive flush when a framebuffer is also an input texture. Fixes some processing effects such as the shadows in the Jak series and radiosity in GTA:SA. It's very costly on the performance. | ||
* ''' | ** '''Disable Depth Emulation''' -- Disable the support of Depth buffer in the texture cache. It can help to increase speed but it will likely create various glitches. | ||
* '''Sprite''' -- | ** '''Disable Safe Features''' -- This option disables multiple safe features. Disables accurate Unscale Point and Line rendering (it can help Xenosaga games), disables accurate GS Memory Clearing to be done on the CPU, and let only the GPU handle it (it can help Kingdom Hearts games), disables special Nvidia hack (it can help SOTC, Fatal Frame games and possibly others too). | ||
* ''' | ** '''Fast Texture Invalidation''' -- By default, the texture cache handles partial invalidations. Unfortunately it is very costly to compute CPU wise. This hack replaces the partial invalidation with a complete deletion of the texture to reduce the CPU load. It helps snowblind engine games. | ||
* ''' | ** '''Frame Buffer Conversion''' -- Convert 4-bit and 8-bit frame buffer on the CPU instead of the GPU. The hack can fix glitches in some games (Harry Potter games and Stuntman for example). This hack has an impact on performance. | ||
* ''' | ** '''Memory Wrapping''' -- Emulates GS memory wrapping accurately. This fixes issues where part of the image is cut-off by block shaped sections such as the FMVs in Wallace & Gromit: The Curse of the Were-Rabbit and Thrillville. This hack can have a small impact on performance. | ||
* ''' | ** '''Preload Frame Data''' -- Uploads GS data when rendering a new frame to reproduce some effects accurately. Fixes black screen issues in games like Armored Core: Last Raven. | ||
* ''' | ** '''Trilinear Filtering''' -- Control the texture tri-filtering of the emulation. | ||
* ''' | ** '''Skipdraw Range''' -- Completely skips drawing surfaces from the surface in the left box up to the surface specified in the box on the right. Use it, for example, to try and get rid of bad post processing effects. | ||
* ''' | * '''Upscaling Hacks''' | ||
** '''Align Sprite''' -- Fixes issues with upscaling(vertical lines) in Namco games like Ace Combat, Tekken, Soul Calibur, etc. | |||
** '''Merge Sprite''' -- Replaces post-processing multiple paving sprites by a single fat sprite. It reduces various upscaling lines. | |||
** '''Wild Arms Offset''' -- Lowers the GS precision to avoid gaps between pixels when upscaling. Fixes the text on Wild Arms games. | |||
** '''Half-pixel Offset''' -- Might fix some misaligned fog, bloom, or blend effect. The preferred option is Normal (Vertex) as it is most likely to resolve misalignment issues. | |||
** '''Round Sprite''' -- Corrects the sampling of 2D sprite textures when upscaling. Fixes lines in sprites of games like Ar tonelico when upscaling. Half option is for flat sprites, Full is for all sprites. | |||
** '''Texture Offsets X, Y''' -- Offset for the ST/UV texture coordinates. Fixes some odd texture issues and might fix some post processing alignment too. | |||
* '''OpenGL Advanced Settings''' | |||
** '''Geometry Shader''' -- Allows the GPU instead of just the CPU to transform lines into sprites. This reduces CPU load and bandwidth requirement, but it is heavier on the GPU. Automatic detection is recommended. Allows advanced atomic operations to speed up Accurate Date. Only disable this if using Accurate Date causes (GPU driver) issues. | |||
** '''Image Load Store''' | |||
** '''Sparse Texture''' -- Allows to reduce VRAM usage on the GPU. Feature is currently experimental and works only on Nvidia GPUs. | |||

**Note that if you simply wish to capture audio (e.g. you like a particular level's music) and you don't want to mess with the plugin or emulator - or you simply prefer a more general solution - you can use [http://audacity.sourceforge.net/ Audacity] to record while the emulator is running - simply configure it to accept audio input from "stereo mix". By the way, if you are running Windows and do not see "stereo mix" in the list of available sources please google for several available solutions (it is a known issue with certain soundcard/motherboard models). Or you could try [http://www.abyssmedia.com/isound7/ this] instead. | **Note that if you simply wish to capture audio (e.g. you like a particular level's music) and you don't want to mess with the plugin or emulator - or you simply prefer a more general solution - you can use [http://audacity.sourceforge.net/ Audacity] to record while the emulator is running - simply configure it to accept audio input from "stereo mix".
