Dolphin, the GameCube and Wii emulator - Forums

Ty guys your explanation is perfect!

One more question, if i drop my display resolution (native is 1680x1050) can i have some improvement??

Depends on the GPU - You should try it at least.

No, your video card is good enough to handle it. Though if you like you can try to turn down Dolphins internal resolution to 2x IR, but it shouldn't make any difference.

No, rescaling the picture to to your monitor size is the least demanding that dolphin does. It won't make any speed difference, and I think you'll get marginally better picture quality with dolphin doing it the right size for your monitor then your GPU leaving it alone than dolphin keeping it small, then your GPU upscaling it before sending it to your monitor. (Although dolphin runs this bit of code on the GPU anyway., so my explanation isn't perfect)

And to those who posted while I typed, he's already dropped it to 1x, and is wondering about changing the full-screen size. I forgot to mention he may be fine with 2x IR, but he got a speedup with 1x compared to 3x.

Ok tried several config but it seems that the only way to run the game with decent graphics and near 100% speed is to set EFB copies to texture losing blue coins and some animation..
changing from 1x to 3x only give me a slight boost ma the game it's almost unplayable cause it's so slow!
I'm wondering which change can help me run games better..an overclocked i7? a new gpu? can't figure it out..

Btw you've helped me a lot and i ty!

Your CPU can't get much better, so if you were upgrading I'd say a new GPU.

Quote:EFB copies to RAM isn't dependant on size of RAM, and frequency barely matters either. Also, if you got any speed-up with a drop in internal resolution, then it means that your GPU couldn't handle the previous IR. When you dropped it you were no longer restricted by your GPU, and then you hit the point at which the CPU was too slow for the current other settings (ie the EFB copies to RAM).

Not completely true. When using efb copy to ram it's normal to gain a little bit of performance when dropping your IR even if your GPU isn't the bottleneck.

@GiammaF
Turn on enable cache next to efb copies.

An overclocked 2500k that cant handle NSMB at full speed?
Try checking your temps also

After some days i have noticed what's my problem!
Simply my gtx 260 doesn't switch to Oc profile, the core frequency remains @400mhz and so i have problems running games at higher resolution..i managed to run it @685Mhz (with some OC) and all games run fine but after some minutes it drops again @400mhz. It's not an OC problem cause i have this issue also at default core frequency.. So i'm gonna try again to fix the problem and i'll try to change my GPU to see if the problem will be still here.

Thank you guys for your interest and your help!

Open nvidia control panel. Add an application profile for dolphin.exe and set the power profile to high performance.
