...I finally have my Dual Shock working correctly. But it seems to have atrociously slowed down PSX emulation. Where I could have games easily run at full speed before, now they are running at least 10-15fps under normal PSX speed. Where GT2 would stay at a constant 60 before, now its like 20-30!!??? If I use PC fps calc, [where full speed would be 30fps], I can run at like a constant 20-23fps. But that really, really, blows man. I've tried turning down the video settings: res, color depth, filtering, etc. and it still wants to run slow as hell. Has anyone got any ideas here?

Yep, its gotta be the controller. It has to emulate all that much more data, stuff or whatever. I just ran a lap on GT2, getting right around 20fps, so it was jerky as hell. Then the replay ran just fine at a contstant 30, beautifully. If anyone's using a Dual Shock and running the emu at full speed, will u please post your specs, configs, and that stuff?

Can you elaborate a bit on "i can't get it to work"? There's like a million and a half different PSX adapters for sale on the web, did you get one of those? I'm using a home made paralell port adapter w/ the Direct Pad Pro 5.0 drivers. Then you have to go to ePSXe's pad config and set it to Digital/Analog. Because Direct Pad works thru Direct X, that's what I've set the vibration to. Then just set all the buttons accordingly...

I use the same thing, but I don't have any slowdowns on ePSXe.

Satan, what does your gamepad config screen look like in the values for the sticks? On mine I have "LY" for the up/down axis on the left, and "LX" for the left/right axis on the left. On the right stick, I have "LRZ" for the left/right axis, and "LZ" for the up/down axis. I did a forum search for "dual shock" and came up w/ a whole bunch of results. Upon reading one, one guy went into RegEdit and changed the values for ePSXe's config under gamepad. If you getta moment, will you check that out for me? I spent a whole lotta time and effort to make this damn controller work, and if its all for shit cause the Emu slows down, I'll be left very pissed...so if you can help that's very cool...

I'm not at home right now, so I can't tell you exactly how I configured it. I did some registry editing to get it to work too, but I don't really reccomend messing with the registry, unless you know what you're doing.

I know what you mean about messing w/ the registry but just changing the settings for the way a gamepad is config'd I wouldn't think would have the potential to screw up my system. Anyhow, changing settings is not a big deal for me. As long as you or anyone else can tell me exactly what to set what to...

I think your home made adapter may just be your problem. When you are using the Dual Shock it is drawing power from your system and thus slowing it down. When you run a replay, you are watching a video and no extra power is being drawn from your system. I use a Dual Shock controler w/a PSX to USB cable made by Pelican Accessories. It works perfectly, all buttons function correctly, and there are no slowdowns at all. The only thing it doesn't do is rumble. Unfortuneately, the cable does not support that particular feature. I'm using Pete's OGL GPU vers. 1.51, Pete's DSound SPU vers 1.10, Pete's CDRom plugin vers 1.5, and the 7502 bios. My system is an Athlon T-Bird 1.2ghz, GEForce 2 GTS, Sound Blaster Live Value, 128 megs of Corsair PC 133 ram, 266 FSB, and Win 98 SE.

Two things:
#1)I have it wired also to a 9v power adapter that plugs in to the electrical outlet, so that's where the dual 'shock' vibration power comes from...
#2)My power supply is a 431watt Enermax. I run 6 80mm fans, 2 120mm's, and a 60 on the CPU. WHich is alot, but that's still a big power supply...I don't know alot about the electronics end though about what components draw what, so I don't think that's my prollem though...

No, power is not a problem. The paralell port can provide enough power for the pad to work, and the rumble function is powered by an outside source. It's a really simple and easy-to-make scheme, but it's also very well done. :)
I believe his problem is somewhat related to his GeForce2 MX. It's a nice card, but it's not the fastest one available. And all the extra processing used by the controller must be slowing down his system, thus causing the framerate to drop on ePSXe. As he said, on the replay it runs pretty fine, but the framerate drops when he's playing.

I want your FSB.

And fluxcapacitor, have you ever tried to run the game from your HD instead of using the CD-ROM?
I do experience some slowdowns when using my CD-ROM to run a game, but not when running it from my HD (that's where a 15000RPM SCSI HD really makes the difference), even with Full VRAM Primitives turned on.


If you have tried it, feel free to disregard my post.

i used to use a Gravis Gamepad Pro for standard PSX pad in ePSXe
recently i switched to a Thrustmaster Rage 3D gaempad for DualShock emu in ePSXe.

no performance hit whatsoever. still at full 60fps most of the time for GT2.
(my sys spec, not very impressive, is in my profile interests section)
