Powerstrip writeup

<< < (3/22) > >>

wpcmame:
Has anyone tried the procedure above and can confirm that it works for others? Anything that needs better description?

Maybe a quick guide could be added like:
1. install powerstrip
2. Edit inifile and add resolutions
3. Add custom resolutions
4. run mame.

If it works it shouldn't take anyone more than 10 minutes to have something that works like the AVGA (except the boot screen of course).

What I didn't mention above is that if you choose a custom resolution as desktop (e.g. 640x288, 768x576) you don't need powerstrip at all once everything is working  Windows will automaticly use the custom resolution timing on startup. This is specially useful if you use the trial version with the nagscreen.

Silver:
Yes I was going to ask - once powerstrip adds resolutions to the registry, is it required at all or can windows just go off the reg settings?

In terms of a setupguide, I imagine the abilities of the monitor used may have an impact.... What horizontal/vertical scan frequencies do those doubled modes generate?

Afraid I've had to pack up my mulitsync and am back on a flatscreen so can absolutely no testing otherwise I'd be on it.

Tried this a couple of nights ago, and couldn't get any games looking great.

The modes were added correctly, but the hwstretch function made everything blurry.
(think of turning the focus on the monitor just a hair off)
It's not that easy to see, but if you have a arcadevga card system next to a powerstrip system, the difference is VERY noticable.
You can tell the cards are doing some AA to the pic and it blurs them out.

Turning hwstretch off gave a sharp pic, but is was shrunken horziontaly.
Also, nohws (No hardware stretch) is incredibly slow.


This was tested with a radeon 9600 pro and a Geforce 5200, both 128 meg agp cards.

The motherboard was a biostar ideq system (linky http://www.biostar-usa.com/ideqdetails.asp?model=ideq+210p

With a semperon 3100 cpu and a gig of ram, windows xp pro.


I cheated and have been doing my testing on a d9200, so I have the full range 15/25/31.5 to play with.
The modes are well and good, but without a way to fill the screen WITHOUT AA on the image, it's not going to look like a avga.

The avga looks so good because to use it correctly, you DISABLE hws in mame.

That is known problem with directdraw. Mame added the option to use d3d just beacuse of that.

Don't remember the options right now but I think it is
-d3d -flt 0
(could be that you need -d3dprescale  as well)

Strange, mame should use software stretch then.

Even more strange. Why would it be slower if the image isn't stretched at all?

dabone:
I'll give those options a try this weekend and report back on how it looks.

P.S. I've got access to alot of different cards/chipsets.

Currently in stock,
ATI X300, X550, 9200, 9600 Pro, 9550, 7000.
Nvidia Geforce MX4000, 5200, 6600,

Anyone have a particular one that they would like tested?
