I see. Would it improve sharpness if:
- the image taken at resolution same as internal resolution
- no texture filtering
- no interlace method

gabest, would it be possible to add another method of deinterlacing? I don't know if this feature already exist, the same one used in virtualdub, discard odd field / discard even field. So if actual resolution is 2048x1536, we use internal resolution of 2048x3072 but only the odd field is displayed.

Sucahyo I don't think pcsx2 has what your talking about. Rumble Roses though uses forced deinterlacing. No matter which of the 3 already present deinterlacing settings used, when making screen shot the vertical resolution is always cut in half.

Other games such as FFX and Metal Gear Solid as far as I'm aware don't use any deinterlacing method and output a progressive scan image. Thats why you get the full vertical resolution when taking screenshots in those games.

As far as I know, every PS2 games has default output as interlace and some of them has the progressive ouput as an option too. I think deinterlacing method is not part of the PS2 games or part of PCSX2. I think it is part of graphic plugin.

I don't know how PCSX2 internal work, but somehow pcsx2 0.81 & gsdx9 v0.8 has progressive output even on games that do not have progressive output enabled.

Notice that on my screenshot, the one with gsdx9 v0.8 do not show interlacing effect. While the screenshot using the recent gsdx show interlacing effect. I use US version of GT4 and I am positive will get the same quality using PAL version, or other PS2 GT version.

I attach cropped picture taken at 2048x1536. See if there are sign of interlacing effect.

The way I see the screenshot of newer gsdx or zerogs, the deinterlacing method is some kind of even and odd field combining. I just thinking if we use double vertical resolution when capturing and discard the even field, and only display odd screen line as half vertical resolution, we get far better quality. It would be better than this option:
- do not process interlace
- copy odd field to even field
- blur the difference between even and old

Gabest is not missing in action. In fact he checked the forum 3 days ago. He simply doesn't have time to code right now I assume.

Besides it's always been like this, the guy obviously codes when he can. He coded a lot during the xmas holiday because obviously he had a lot of time but.. before he'd been away for quite a long time.

To sum it up, be grateful his plugin works so well, and wait for the time when he will have more time to code again. It's not like he's paid to code gsdx you know.....

I've used vLite with Vista with latest build of SP1 and removed 3.8GB of useless stuff from it and when it was burnt onto DVD the capacity was only 1.14GB. I've got all unneeded services stopped etc. and it's still ~5% slower in average system wise but in some games on PCSX2 there can be a benefit by DX10 plugin but mostly Vista is slightly slower by about 5%.

DBZ3 Budokai Tenkaichi 3 like mentioned above I had only 3~5 fps more in Vista (45~50 in XP, 48~55 in Vista) than in XP comparing with an internal resolution 1600 x 1200 which is high enough to be GPU limited definitely not some 20%+ increase like mentioned above. I'm dualbooting Vista SP1 with tweaked XP SP3.

I'm using vista ultimate 32 bit, with classic theme, true that i got just about 5 fps speed increase in 1600x1200 because gpu limited, i test using vista for both dx9 and dx10 because i've uninstalled xp now

using 1024x1024 in dx9, i got 55-62fps avrg , using dx10 avrg is 70-75fps,
most of time dx10 has about 15fps more than dx9 using same place and fighter, except at freeza's ship at space, dx9 i got about 65fps and dx10 is around 70fps, strange

Well then it's a given, if you have DX10 supported card, and it's a good one, not on-board or low-end, the DX10 seems to be faster in many games, a good increase.

Say, 5% boost as the medium increase over all games is STILL 3 FPS more. Combine that with tweaks in future versions, and optimizations and it's def the way to go.

20% boost would be 12 FPS more...that's no joke.

I found a way to change the window mode default resolution of gsdx9 version 0.8 and 0.9. The original resolution of both is 1024x1024, I don't know if this related to D3D internal resolution or not. Using this information I capture the image of PS2 bios at 2048x1536 at window mode.

The quality of v0.8 is much better than v0.9. On 0.8 the cube line is sharp and thin, while on 0.9 the line is blurry, thicker and jaggy. So atleast on my pc the result of v0.9 should be much worse than v0.8 when rendering polygon. I don't have other game besides GT4, but I am thinking that other car game would have much better quality on v0.8.

If the current version has image quality as bad as v0.9, I hope gabest can add an option for this high quality polygon rendering on next version.

Can anyone post the cropped screenshot of bios using latest gsdx and highest quality setting (but no interlacing method)? It would be preferable if you capture at resolution 2048x1536 and cropped the picture when uploading. I take the screenshot using fraps at windowed mode with "window resolution" at 2048x1536.

THe only difference in those 2 pics is 0.9 using a lower internal resolution. The "thick" "jaggy" lines are a symptom of low resolution.

Ckeckout these screenshots. Both are from the newest version of GSDX. Version 0.1.7 , to see what I mean.

I don't have the hardware. But seeing the screenshot of GT4 using new version of gsdx so far, I will still suggest anyone to use v0.8.

In gtplanet there is a section for GT4 hybrid, a way to modify your car outside what the normal way can. Hybrid in GT4 can be done faster using pcsx2.

Many newcomer on this section just wish to run GT4 on PC, they don't wish to spend any money to do this. They already have real hardware, so they don't have any reason to upgrade their system. I usually tell them to use whatever version that works. For now it is either pcsx2 v0.81+gsdx9v0.8 or pcsx2 v0.92+gsdx9v0.9.

But there are people that have better hardware that surprised with so much better quality of v0.8 and wish to see the same quality in newer gsdx version.

If gabest read this, My wish:
- newer gsdx have quality equal or more than gsdx9 v0.8
- if post processing exception need to be added for any version of GT4 or GT3 please add an option to turn on/off post processing
- bring back fixed pipeline support in newer gsdx
- rerelease gsdx9v0.8 with red and blue color swapped.
- rerelease gsdx9v0.8 in pcsx2 0.9 specification so I can run gsdx9v0.8 with pcsx2 v0.92.

Thanks for the picture. I see that new version can render polygon fine. But why is it so blurry? can't you make a crispier screenshot? Is that using highest quality?

I also attach the scaled down version of V0.8 bios.

when are you going to need 100GB of RAM?

He meant to say 1.00GB of RAM, as in 1 GB, he just copied it from the System control panel...don't blame him, and I'm sure you knew that already, don't spam.
