Jade Dynasty – Increase FPS

(I have rectified my answer. To clarify: every process gets 2 GB of virtual address space. All processes combined can't exceed 4 GB of physical memory)

Actually, yes. There are many misconceptions about the memory limit in 32-bit Windows OSes.

First of all, when I say RAM, this includes every kind of RAM. So not just regular, but also your video RAM. Only physical memory though, not swap/paging.

The maximum available amount of RAM per process for a 32-bit OS is 2 GB. If you have a 64-bit OS, a 32-bit process can allocate up to 4 GB.

Additionally, the entire OS can only address 4 GB for every process combined, while 64-bit OSes can allocate 8 TB.

Also interesting is that this limit adds up to the paged pool. This means that a 32-bit OS cannot use more than 4 GB total, which means 6 GB for all applications including virtual memory. Of course, this has nothing to do with RAM, because the other 2 GB would be stored in the paging file, limited to your hard-drive's speed.

The main fork of Dolphin isn't optimized for running Super Mario Galaxy 2. You should try this:

Make sure you have - The latest stable build of Dolphin (64-bit if you have a 64-bit machine) - AA CPU with SSE2 support.

then

Turn off/lower to minimum

• Limit by FPS
• DSP on Dedicated Thread
• V-Sync
• Log FPS to file
• Ignore Format Changes
• Anti-aliasing
• Anisotropic filtering
• Post Processing effect
• graphics options: Advanced tab: all checkboxes
• DPSLLE on Separate Thread

Turn On/raise to maximum

• Optimize dolphin settings. (Online resources: FAQ, SMG2, Wiki Manual, Performance Guide)
• Use DirectX if possible
• Internal Resolution: 1x Native (640x528)
• Rightclick Game Window -> Properties -> Alternate Wiimote Timing
• Config -> Enhancements -> Enable Scaled EFB Copy (may be unnecessary)
• Enable Dual Core
• Set CPU Emulator Engine to JIT or JITL (if latter may has issues, use JIT
• Enable Idle Skipping
• Force Texture Filtering
• Disable Fog
• Per-Pixel Lighting
• Set EFB copies to Texture
• Set Texture Cache to Fast
• Cache Display List (may crash, try and on and off)
• Disable Destination Alpha (may crash, try and on and off)
• OpenMP Texture Decoder (in rare instances it can "max out all cores" and hurt more than it helps)
• Fast Depth Calculation (may cause flickering textures, try on and off)
• OpenCL Texture Decoder
• Fast Depth Calculation
• OpenMP Texture Decoder
• Vertex Streaming Hack
• DPS LLE Recompiler
• XAudio2
• Reduce detail in your graphics card settings to improve performance.
• Hide mouse cursor
• DSP Emulator engine to DSP HLE Emulation (fast, but you may encounter audio glitches, if so, you may want to switch to DSP LLE Recompiler which is slower but more accurate)
• If using DSP, use this guide to dump DSP files with a Homebrew-enabled Wii (if you have a Wii, that is)
• Game Config: Speed up disc transfer rate

or

• Try another fork or unstable build of dolphin
• Repeat the dolphin setting optimization for that build.

or

• Get overpowered hardware to cope with running the software.
