bsnes v030 released

Nvidia will be my next card, that's for sure. I'm actually waiting on a new nvidia chipset to be released so I can get my penryn and decent onboard video.

Even more surprising, it's about ~2% faster than before. Even though it's technically even more complex now with three writes instead of two. Makes no sense at all, but I won't complain. Getting 122fps now on Zelda 3 load screen.

I just compiled the new wip and I am getting 2 fps speed increase + the audio seems much more synced

good work byuu

Onboard video has never been a source of "good things" to come.

I also recommend enabling triple buffering. With that, video is perfectly smooth and audio is ~99.5% perfect. So, so close. A slight cpu.freq change and you can probably get it perfect.

Could that change break games?

vsync shouldn't affect any games.
Fiddling with the cpu speed should be ok too, as long you don't make any large changes. After all, few, if any, actual units ran at exactly that speed, they where just a tiny bit off in either direction. Bsnes uses the ideal speed, reality did not.

New WIP, which converts the S-DSP ring buffers to an internal class object. Surprisingly, it actually does make the code a bit nicer to look at, although it's kind of unfortunate I can't hijack operator[]=, heh. I'd be forced to use modulus for that.

ATI Radeon X300LS:
Direct3D = 64fps
OpenGL = 24(!!)fps

... as if we needed another reason not to buy ATI products. What the hell was AMD thinking, buying them?
Better yet, why do people buy ATI products? Laptops, I can understand. But for desktops?? Seriously. That performance is so terrible, you couldn't even play OpenGL games with that. We really need more OGL titles to rape ATI on benchmark tests, so that they'll get their heads out of their asses.

The main problem right now is that most titles are built with D3D, so that's not gonna happen anytime soon. AMD(AMD bought ATi a while back) has always half-assed their Open GL support. Why, I don't not know. Nobody does outside of the company. A few years back, they were promising a major Open GL rewrite that was supposed to bring their Open GL support up to speed.

Then they delayed it. Then they said "Well, it will be slowly phased in."

It never happened.

Right now, AMD has been having serious driver bugs in a lot of things. It's gotten to the point that they were actually selling video cards that did not work in most systems(Their D3D support was broken on all AGP based cards. They sold 2400 Pros while knowing about this problem.), and that things listed as being fixed in their releases notes might not be fixed!

Fact of the matter is, they are an embarrassment to the 3D industry right now because of this. Unlike nVidia, they seem to be mostly concerned with making sure relatively recent games work. nVidia was like that for a while(Anybody remember the GeForce FX fiasco?), but got their head out of their ass, and started fixing their drivers.

Edit: I tried MK2's character select screen on Verdauga's build and the latest WIP.

I got a 28-29 FPS improvement! From 106/0 to 135-134/0.

I wonder if they fixed the GLSL modulus bug yet

I.S.T. · Post by **I.S.T.** » Wed Mar 26, 2008 1:07 pm

I wouldn't know.

Turning on OGL slowed things down for me by about 8 FPS. I don't know why. I've got a GeForce 8500 GT...

I'll try tweaking my OGL settings. Might have something on that shouldn't be on.

Edit: Nope, rivatuner is telling me the settings are correct.

I wouldn't know.

Well basically, the issue was with a custom shader. Part of the issue is that a simple solution to the algorithm of this shader was using a modulus operator. However, at the time the shader was tested, ATI cards didn't support it at all, while NVIDIA cards ran the shader fine. So in the end, we had to use all kinds of hacks to make up for ATI's shoddy drivers.

For reference, this issue I noticed is related to dithered alpha rendering in the Glide3x wrapper bundled with Glide64. I recall other issues we had with OpenGL and ATI cards (like not supporting certain texture formats).....

Depends on what you need it for. I don't play new PC games. I pretty much do OpenGL counterstrike and emulators. An onboard 8200 would be a massive upgrade over the x300se that I'm using now.

Blast you ATI cards.

v0.30.04 gets 25fps on the Chrono Trigger intro with speed regulation enabled, and 35fps when it's disabled with the OpenGL setting.

Why are there wip links to http://byuu.cinnamonpirate.com/temp/bsn ... _wip08.zip
but not for 30.04?

Because private WIPs are intentionally stored in a different place than public ones?

Byuu, why would you understand if people buy ati in laptops, when some OEMs use nVidia as well?

Unless nVidia is shit in laptops of course.

I thinks it's not a good idea to post any and all WIP links publicly regardless how old it is.

neo_bahamut1985 · Post by **neo_bahamut1985** » Wed Mar 26, 2008 10:50 pm

Okay, so, then why are there wips posted for version 0.28?

Because the WIP page only contains the latest build, and we had to test when a change was made. (as it turned out, between 0.028 and 0.028 wip 03)

Verdauga Greeneyes · Post by **Verdauga Greeneyes** » Wed Mar 26, 2008 11:47 pm

Hmm, another question for you, byuu. Where (in what file) are pitch and outpitch defined? And where are the filter functions called? (maybe both should be obvious, I'm not that experienced with code organisation)

shimatta...I did want a slightly faster build, even if it is a beta.
