  // If the same texture address is used several times during the same frame, assume the address is

  // that hasn't been used for the same frame, then overwrite it, in order to keep the cache as
 | 
						|
  // small as
 | 
						|
  // possible. If the current texture is found in the cache, use that entry.

  //      Encodes the requested EFB data at its native resolution to the emulated RAM using shaders.
 | 
						|
  //      Load() decodes the data from there again (using TextureDecoder) if the EFB copy is being
 | 
						|
  //      used as a texture again.
 | 
						|
  //      Advantage: CPU can read data from the EFB copy and we don't lose any important updates to
 | 
						|
  //      the texture
 | 
						|
  //      Disadvantage: Encoding+decoding steps often are redundant because only some games read or
 | 
						|
  //      modify EFB copies before using them as textures.
 | 
						|
  //
 | 
						|
  // - EFB to texture:
 | 
						|
  //      Copies the requested EFB data to a texture object in VRAM, performing any color conversion
 | 
						|
  //      using shaders.
 | 
						|
  //      Advantage: Works for many games, since in most cases EFB copies aren't read or modified at
 | 
						|
  //      all before being used as a texture again.
 | 
						|
  //                 Since we don't do any further encoding or decoding here, this method is much
 | 
						|
  //                 faster.
 | 
						|
  //                 It also allows enhancing the visual quality by doing scaled EFB copies.
 | 
						|
  //
 | 
						|
  // - Hybrid EFB copies:
 | 
						|
  //      1a) Whenever this function gets called, encode the requested EFB data to RAM (like EFB to
 | 
						|
  //      RAM)
 | 
						|
  //      1b) Set type to TCET_EC_DYNAMIC for all texture cache entries in the destination address
 | 
						|
  //      range.
 | 
						|
  //          If EFB copy caching is enabled, further checks will (try to) prevent redundant EFB
 | 
						|
  //          copies.
 | 
						|
  //      2) Check if a texture cache entry for the specified dstAddr already exists (i.e. if an EFB
 | 
						|
  //      copy was triggered to that address before):
 | 
						|
  //      2a) Entry doesn't exist:
 | 
						|
  //          - Also copy the requested EFB data to a texture object in VRAM (like EFB to texture)
 | 
						|
  //          - Create a texture cache entry for the target (type = TCET_EC_VRAM)
 | 
						|
  //          - Store a hash of the encoded RAM data in the texcache entry.
 | 
						|
  //      2b) Entry exists AND type is TCET_EC_VRAM:
 | 
						|
  //          - Like case 2a, but reuse the old texcache entry instead of creating a new one.
 | 
						|
  //      2c) Entry exists AND type is TCET_EC_DYNAMIC:
 | 
						|
  //          - Only encode the texture to RAM (like EFB to RAM) and store a hash of the encoded
 | 
						|
  //          data in the existing texcache entry.
 | 
						|
  //          - Do NOT copy the requested EFB data to a VRAM object. Reason: the texture is dynamic,
 | 
						|
  //          i.e. the CPU is modifying it. Storing a VRAM copy is useless, because we'd always end
 | 
						|
  //          up deleting it and reloading the data from RAM anyway.
 | 
						|
  //      3) If the EFB copy gets used as a texture, compare the source RAM hash with the hash you
 | 
						|
  //      stored when encoding the EFB data to RAM.
 | 
						|
  //      3a) If the two hashes match AND type is TCET_EC_VRAM, reuse the VRAM copy you created
 | 
						|
  //      3b) If the two hashes differ AND type is TCET_EC_VRAM, screw your existing VRAM copy. Set
 | 
						|
  //      type to TCET_EC_DYNAMIC.
 | 
						|
  //          Redecode the source RAM data to a VRAM object. The entry basically behaves like a
 | 
						|
  //          normal texture now.
 | 
						|
  //      3c) If type is TCET_EC_DYNAMIC, treat the EFB copy like a normal texture.
 | 
						|
  //      Advantage: Non-dynamic EFB copies can be visually enhanced like with EFB to texture.
 | 
						|
  //                 Compatibility is as good as EFB to RAM.
 | 
						|
  //      Disadvantage: Slower than EFB to texture and often even slower than EFB to RAM.
 | 
						|
  //                    EFB copy cache depends on accurate texture hashing being enabled. However,
 | 
						|
  //                    with accurate hashing you end up being as slow as without a copy cache
 | 
						|
  //                    anyway.
 | 
						|
  //
 | 
						|
  // Disadvantage of all methods: Calling this function requires the GPU to perform a pipeline flush
 | 
						|
  // which stalls any further CPU processing.
 | 
						|
  //
 | 
						|
  // For historical reasons, Dolphin doesn't actually implement "pure" EFB to RAM emulation, but
 | 
						|
  // only EFB to texture and hybrid EFB copies.
