Dolphin, the GameCube and Wii emulator - Forums

Um, Metroid Prime REQUIRES EFB to RAM. Without it, the Thermal and X-Ray Visors behave improperly. In fact, EFB to Texture is explicitly disabled in the game INI for this reason.

LLE Interpreter is the worst option when it comes to select an audio engine.

Last Dolphin version with DX9 available is 4.0-146. Remember that.

The other backends have lots of audio lag. XAudio2 gave the best results for me.

5). Internal rendering does make a significant difference - the graphics becoming increasingly choppy as I crank it up. Using OpenMP doesn't seem to improve this, and OpenCL makes the emulator hang - so I don't use either of them.

Set anisotropic filtering to x16, always. You'll have to find the perfect combination of internal resolution and antialiasing for each game. I usually use 3xIR+4xSSAA, but 2.5xIR+4xSSAA for Twilight Princess (with a huge texture pack). Your GPU is much better than mine, so I think you should use 3xIR+4xSSAA minimum.

Use LLE recompiler and DSPLLE on separate thread. Only a few games have problems with that.

It's a pity that your CPU isn't a k version, but I think sou can still overclock the BCLK instead of rising the multiplier.

Thanks for the detailed reply. Really appreciate it.

Yeah, I thought I was buying a 4770k. Didn't appreciate the difference until after the rig had been assembled... ho-hum. Not a bad chip, all the same...

... would you mind telling me how to set-about overclocking it? Can it be done through firmware? Because this is a very specialised machine (it's actually a bespoke arcade cabinet), so getting at the CPU would be a ball-ache.


Also, re DX9 - does this mean that I won't be able to use more advanced builds of Dolphin until OpenGL and DX11 support improves?

Cheers,




DH.

On most motherboards, you just hit delete/F12/F9/whatever it says when it's booting, and you'll get into your BIOS. If the board supports it, you can then set the BCLK and Multiplier (if you have the K version). Usually BCLK OC'ing doesn't have much headroom, but it's supposed to be more viable on Haswell than Sandy and Ivy. However, not all motherboards support BCLK or multiplier overclocking, so you'll need to check.

This corrupts graphics is some games, e.g. Legend of Zelda Twilight Princess and Resident Evil 2/3

FYI, you don't even need to be using DSP LLE for Metroid Prime. The current HLE sounds identical to LLE for 99% of games. (Seriously, when delroth wrote it he compared audio dumps from HLE and LLE and found absolutely zero difference.) There are exceptions (e.g. any game that uses the Zelda µcode, the HLE for which hasn't been touched by delroth and is comparatively awful), but Metroid Prime should have no problems. (If you notice any audio difference/breakage that isn't just placebo, feel free to file an issue on the Google Code issue tracker.)

Also, usually OpenGL with "Vertex Streaming Hack" checked ends up being as fast as or faster than DX9 on Nvidia GPUs. Try that out, see if it's faster.

Just a clarification that while opengl is fast with vertex streaming hack, it is usually slower than direct 3d when a game needs Efb to Ram to run. Efb to Ram seems to run slower than all the other backends here at least when using open gl (windows 7 x64 , 560 ti with latest drivers).

Thanks, everyone.

Remarkably, Dolphin has completely lost its ability to throttle a frame-rate. All I did was change from DX9 to OpenGL, and now it's crocked. Even when I change it back to DX9, it still runs far too quickly. Even when I set a framelimit.

The only way I can slow it down is by changing the video backend to Software. That properly makes it chug...!!!


Do I need to reinstall Dolphin, maybe?
