Optimization

[IceCold]

The emulator works great and I know you people are doing the best you can to do it better but you need to work on the optimization.I mean:

intel core i7 2.67 ghz
6gb ddr3 1333
Gtx 260 core 216 superclocked

To Lag on Zelda Twilight Princess and other games?I mean come on I doubt that U will find better computers in a normal family.You need to make the emulator eat less resources cause at the moment the emulator is very "hungry".

I got an Intel i7 920 as well and the emulator works ok on most games (ok means 20-30 FPS average). PCSX2 runs better on my machine though.

Dolphins major problem is that it only supports 2 cores, which makes an i7 920 (non overclocked) inferior to a good Core 2 Duo. According to the devs there's no way to deliver better emulation using 4 (or more) cores, so I doubt we'll see at least Quad Core emulation very soon...

20-30 FPS you call ok?
I am used to 100+ FPS from the PC games so a 30-40 FPS from some emulator games kind of makes me feel like I have a 'crap' computer,although I know it's not true.

Maybe the Dolphin developers will consider optimizing the emulator so it will work better and eat less resources.

And also I saw people that complains about 1GB+ memory a solution whould be that the dev will add some options for the people with weak PC's so they could play too.(it's not imposible,maybe time consuming but not imposible)

i like when people have no idea what they're talking about

When I said 20-30 FPS, I was talking about Dolphins internal FPS counter (which is messy). 30 FPS can be considered full speed. So, yeah, most games I play on Dolphin (and which aren't broken, like MGS The Twin Snakes or Fatal Frame 4) got an average speed of at least 20 FPS, according to Dolphin.

And its GHz that matters, not amount of cores that cannot be supported by dolphin because of GC/Wii hardware architecture. You'd better OC your CPU get an IL build and play with dolphin settings to make games run on a decent performance level.

just because you wasted a lot of money does not mean your machine is any good.

i7 920 without overclocking is really not that fast.
you can overclock a stupid 50$ cpu to higher speed.

in fact, many overclocked c2d from first days (summer 2006) still outperform a 920 at stock clock.

its not.

it runs much better compared to ps2, ps1 or n64 emulation.

wii has >700mhz, ps2 got 300.

for example try to run psxe2 on a i7 downclocked to ~1,2ghz. good luck with that.

If you want optimization, then implement stream caching, ZTP slows down because of the geometry payload that occurs basically on every frame. Dolphin spends most of its time loading all the vertex loading, gamecube can use over 8 vertex loaders and they all do their work every second basically. This technique is fast on hardware because the hardware spends time just doing that and nothing else, else for software, this isn't a good approach to mimic something that only good in performance on dedicated hardware, so we need to make a vertex array hash table and cache them, they way it saves time on dolphin from loading too much every second and same can go for Display Lists, they could be cached and then point to them stored in ram, this is how Gamecube does it, I am not sure if Dolphin does this already.

Since rene isnt here and blinkhawk isnt around i will post for them

that was an ignorant comment, I7 920'S ROX0R TEH BIG ONEZ111

NOOBS! allways speaking bullshit, clock speed doesnt mattter, dude your cpu is way better than mine so you should have no problem running games

Me:

Fuck all of you

[boogerlad]

I agree with the second part. It was pretty stupid to say that clock speed is what matters, however, a e5200/equivalent quad. or phenom II overclocked to about 3.5ghz and up will match or overcome an i7.
