Can my PC run these games? Running Dolphin in itself can be loaded and run off of 10 year old hardware. I believe the program in itself does not require much to run. Considering each game has its own set of requirements for running well within emulation. Maybe I'm being a bit of an ass here but think about it. That should be the more realistic question to ask. Emulation is majorly based upon CPU and not so much GPU. I would say its 90% CPU and 10% GPU give or take. Most games in dolphin can run off of 6 year old GPU's but if the CPU isn't up to snuff games won't run well or at all.
Shouldn't the question be...

When people ask if their system can run Dolphin it usually imply they wanna know if the games they plan to play will work fine. That's why they list them or (more often) they're asked to list them. And the answer is often (always?) this game will work just fine or this game is too demanding for your system. Now a game can work fine but not perfectly and a demanding game can be playable. Depends on the games. Depends on the systems

Most of the people here in Hardware are veterans to emulation and Dolphin specifically, so we do know the distinction between running a program and running it well. You will often find some of our responses reflect that, in a form along the lines of "Can you run Dolphin? Yes. Can you run Dolphin fullspeed? ... " And of course the last part varies depending on the hardware and games mentioned.
New users here in Hardware are usually new to either emulation in general or just Dolphin, and they're the one's posting questions in the form "Can I run Dolphin" more often than not. It's not like we'll ever be able to educate everyone before they post here (just look at those who don't read the Forum Rules before making their first post) and even when someone does learn the difference, eventually someone else will come along who doesn't know it. 04-03-2013, 12:47 AM

Your terminology is more accurate yes. That's basically what they are asking though. They just don't phrase is correctly, but we know what they mean. fade2black001 Wrote:Emulation is majorly based upon CPU and not so much GPU. That's what we generally tell people since it's a nice simplification for those that are not as familiar with the inner workings of modern emulators. A more accurate description would be "fullspeed emulation usually requires more of an increase in cpu performance relative to the hardware being emulated than gpu performance". The reason for that is that cpu and dsp emulation is entirely done on the cpu. But gpu emulation is done on both the cpu and gpu with most of the more demanding tasks being done by the gpu. The GPU is basically just used for 3D rendering tasks that tend to be highly parallel, map reasonably well to the native hardware, and are almost always emulated HLE style (whereas cpu code pretty much has to be emulated LLE style). The exact amount of processing power needed from the native cpu/gpu will depend on what the emulated cpu/dsp/gpu are doing. It just so happens that the emulation of gamecode (which takes place on the cpu) tends to be the bottleneck. I sure as hell don't want to explain all this to every person who asks though so it's easier just to tell them what you just said. I mean technically speaking the gpu is still doing more work in terms of operations per second. It's just the enormous amount of extra overhead on the cpu side that forces you to have a more up to date cpu than say a PC game. And the gpu overhead is still enormous as well, just not as enormous. Then again all I'm doing here is explaining reasons and context which is unneeded for most users. fade1black001 Wrote:I would say its 90% CPU and 10% GPU give or take. This doesn't really make sense. I don't know what you're measuring or how you're measuring it. fade1black001 Wrote:Most games in dolphin can run off of 6 year old GPU's but if the CPU isn't up to snuff games won't run well or at all. It's more about how fast the GPU is than how old it is. A very high end 6 year old card will run most games at fullspeed, so you're correct in that regard. I just don't like to use age as a measurement of performance unless I have to since while older hardware is generally slower it's not always slower.
