Dolphin, the GameCube and Wii emulator - Forums

Hi everybody,

It is my first post here so I want to thank the Dolphin Team for the good work.

Since the new version (4.0) Dolphin is a bit weird.

It run very smooth & fast on Directx 9 & Open GL but I feel that the scrolling/animation is not smooth as before.

My computer is the following:
- Windows 7 x64
- I7-4770K @3.5 Ghz
- 32 Go of memory
- Geforce GTX 660
- I installed latest Directx 11 and graphics's drivers.

For example, I tried Luigi's Mansion on my computer in fullscreen or in window modes with the following settings :
- video : 1600 x 1200
- vertical syncro
- internal resolution 2.5 (1600 x 1320)

All others settings could be set at maximum but the FPS is always at 60 fps on menu or 2D scenes and 30 fps on 3D scenes (why this difference?).

I launch the Luigi's Mansion game and see the 3D introduction.

With Directx 9 & Open GL scrolling are very smooth but there are little graphical errors (for example around the mounth of Luigi. On previous version it was perfect).

I do the same with Directx 11 (same graphical settings).

Whereas FPS is at 60 or 30 fps, the scrolling (I mean the animation when the camera is moving) is not smooth as before. It like some intermediate frames between 2 calculates frames that exists before are actually missing on Directx 11. It is hard to explain but I feel like this is not smooth and frankly talking it is not so good as before.

Then, there are also small graphical bugs on Directx 11. So I can conclude that graphical bugs are more a problem coming from Dolphin (I do not remember the previous version of Dolphin had this kind of graphical bugs).

About the scrolling, I cannot understand because my computer is fast enough and with Directx 9 & Open GL I can use more heavy graphics or resolution without having this problem.

I also have this feeling with Twilight Princess (not as smooth as before but no graphical bugs).

I had the feeling beefore that the Dilphin Directx11 setting does not support correctly "high" resolutions (internal resolution x2 and more) for some reasons (?).

I really want to understand why Directx 11 setting is like as I described and how to correct this.

Best regards.

Seems to be a new trend to get 32GB of RAM for much money to do nothing.

Anyways, OpenGL is the plugin you want to use because OpenGL has a hack for NVIDIA cards that uses a loop-hole in the driver that speeds up the whole backend.
If it's still possible, sell that 32GB RAM and just get 8GB RAM. I assume you aren't a Photoshop/Bitcoin/folding@home/Adobe Premier mastermind. You could have gotten a far better GPU for all that money.

Thank you for the anwser,

Are you saying that it is a problem with speed of the graphical card (GPU)?

If it was so, why the Directx 9 setting is as smooth as the Open GL one?

I can also set graphic at full details using Directx 9 without having this kind of problem. For this reason I do not understand why Directx 11 is not so smooth (setting on lower details does not affects the animation problem).

I do not particularly want to use Opengl. I just compare the best performance cost of each setting regarding the global quality : directx 11 consumes more CPU & it is not smooth & the visual rendering is no so different with Directx 9 (for a common human).

Then, I am not talking about Dolphin, but on PC games like Tomb Raider 2013 using Directx 11, I do not have this kind of problem. So I am wondering it is really a problem of the GPU performance of my card.

By the way, I do not want to spend a lot of money for graphic card just for Dolphin or some games^_^;

I bought 32 Go for the reasons that I like editing video or audio. Then, with a lot of ram it also possible to make virual hdd directly in memory... there is a lot of way to use memory that is not needed by Windows ;-) May be there is a trend about it but I do not really know. I just made the computer I wanted. That is all.

You likely got Dolphin from the wrong site. You should get it from the official site - https://dolphin-emu.org/download/

If you had gotten it from the official site you'd have noticed that 4.0.2 is out, with a bunch of nasty bug fixes for 4.0. And of course it has development versions that go well beyond 4.0.

Thanks for the answer.

I am sorry I forgot to say that I notice this problem since the Dolphin 4.0, I have also installed the latest 4.0.2 version.

I thought it will be better with the latest version but no. That is why I decided to post today. I do not know if it is only a problem with my computer...

The mouth of luigi being glitched is because you're using cache display lists, which is a hack. That's your own fault.

Luigi's Mansion runs 30 fps in 3D scenes, that's not a glitch. That is just how fast it runs.

The mouth is glitchy for me even when "cache display lists" isn't enabled.

IIRC it has been like this since you guys removed a feature years ago. Don't know what it was called but it fixed/broke Luigi's mouth depending on what you set it to.

Something like "Optimize XYZ"

It was then removed, fixed, but something appears to have broken it again. I'm getting the same glitch.

Unable to reproduce, assuming you guys have something set wrong.

Found it: Optimize Quantizers was the thing that fixed it.

Some devs found a workaround that fixed it without it, but it seems to be broken now.
