Yes, a ramdisk will help - but Dolphin still needs to process the shader so the stutters will become shorter. Have a search on these forums, a ramdisk has been suggested as a way to speed up Dolphin. You'll have to put the iso on the ramdisk too. 11-30-2010, 02:14 AM

Yeah it turns out my RAID 0 setup was utterly retarded. The http://en.wikipedia.org/wiki/TRIM command never gets run with such a setup, so performance degradation was way above normal and my write speeds were slower than that of my 5400RPM HDDs. I'm getting better performance now as far as stuttering but it's still sort of there, but I'll look into that. It was definitely a drive issue and not a graphics issue. I've got the two drives running separately now.
Does Dolphin really need to use the drive for such caching, though? I've got 6GB of fairly fast RAM, I mean, screw a RAMdisk, why doesn't Dolphin just cache such data directly to RAM? Or at the very least I wish it could be configured as such. Makes me want to contribute to the project, but I am not that great of a programmer and don't know jack about emulation. The stuttering seems to be based on drive latency/bandwidth, which is probably why stuttering is "normal" for most users as I imagine a good number of them are using HDDs. I'd much rather Dolphin take advantage of the generous amounts of RAM as presumably that would be much more responsive for systems that could handle it. I'll look into a RAMDisk, though, if it might get me smoother gameplay.

As you can see in my sig, I'm running similar hardware as you are. I have not had stuttering problems. My bottleneck would be my HDD, it's pretty slow, but even so I don't notice anything.
If anything is you're bottleneck it's probably your GPU. However, I've had stuttering problems with pc games in the past, which should've run just fine on the hardware at the time. And most of the times it was caused by some random software running in the background. Once that software was shut down or removed altogether, it ran fine. If you're running any norton software (in fact if ANYONE is running any norton software xD), please deinstall that SHIT. It will kill your performance.

NO NO NO! I don't mean what are ssds, I mean what brand/product/controller?
I'm not that stupid =P 11-30-2010, 03:42 PM

Quote:Really?? I read they were not as secure as a hard disk... What do you mean by secure? When I say reliable let me explain what I mean. If you take a hard drive and smash it against the nearest wall as hard as you can you will probably break it since it has moving parts. If you do the same thing with a SSD not only will the drive be fine but you won't even damage any of the data on it since its essentially just a bunch of chips on a circuit board. Unless you apply enough force to snap the circuit board in half your data will be fine. This is why they are starting to become popular with high end laptops, since they are basically immune to fall damage if you drop your laptop....nothing...data is still safe. Quote:NO NO NO! I don't mean what are ssds, I mean what brand/product/controller? Apologies. I misunderstood. Quote:Isn't that kind of unfeasible given the size of an iso? Not really. Even windows 7/vista will rarely use more than 1GB of memory and dolphin only needs a couple hundred megabytes of memory. Since most desktops and even laptops today have 4GB of ram you can easily create a 1.6 GB ramdisk for a GC iso and dolphin and still have 2.4GB leftover, which is more than enough. You could even give dolphin it's own 1GB ramdisk and still have enough ram. Wii games on the other hand...you will need 8GB of ram instead of 4.

Well I am baffled. After getting rid of the raid array and clean installing windows I distinctly recall the stuttering problem to have been reduced significantly. However now as I go back to the game it is as bad as ever. The benchmarks for my drives are much faster now but there is no increase in performance whatsoever.
To me poor graphics performance would translate into low framerates and consistently low or shaky framerates. The stuttering is there right down to the audio. And I can't even get good performance at 640x480 with this card? I just don't want to drop $200 on a new graphics card and get nothing out of it and then have to return it and probably lose like 15% on the refund. Maybe I'll grab a card from a brick and mortar store like Micro Center so I can return it easily. http://www.newegg.com/Product/Product.as...6820211419 these are the drives I have. I have the latest firmware installed. I don't have any kind of software like virus protection running in the background. EDIT: OK I'm heading to Micro Center today to get the GTX 460 to see what happens. If it works I'll keep it (or order it from Newegg for cheaper) and if it doesn't I'll know there's something seriously F'd up with my CPU/RAM/SSD performance.
