The small alignment issues are the result of rounding.
D3D uses floating point coordinates, the PS2 GS is integer.
If we want to use a GPU to render graphics, we need to convert from integer to float.
Currently there's no perfect fix for this problem.

i think the bigger issue is the fact it isnt just integer, but 12.4 integer, obviously being 4 decimal places.

guess you could do in a pseudocode kinda way

float = int >> 4;
float += ((1.0f/1000) * (int & 0xf));

Is there any option to make Hardware mode to look EXACTLY like Software without all the fancy Shaders and Lighting effects?
If it could look like Software mode but take the load off from the CPU to the GPU it would be ideal.

Will it be difficult to just move the Video-Output code in software mode to the GPU?

Thanks.

More like impossible.

GTA: San Andreas.

Lighting bug in Software Mode.



As you can see there is an overlay of translucent picture over the main screen.

Sorry about me over-flooding the forum with bugs, I just want to make it better.

That's not software mode, there is no way in hell your gs usage on that game would be 15% in software. I know for a fact that bug is only present with hardware scaling.

Well, the image above IS in Software Mode.
Clamping Modes set to EE/IOP = "Full", VUs = "Extra+Preserve Sign".
MTVU enabled.

Software Mode and GS jumps around 20% (Although I don't know what the hell it means).
When I disable Frame Limit I get 85fps.
Using 6 threads (look for my PC specs for reference).

Hardware Mode GS jumps around 15%
When I disable Frame Limit I get 100fps.

Hardware Mode:



You can also see here the texture stretching problem on the font.

Jak 3
One of the heaviest games in PS2 or on PCSX2 in terms of graphics and processing.

Shadows problem with Software & Hardware mode.
Eyes problem in Hardware Mode only.

Software Shadows:


Hardware Shadows and Eyes problem (supposed to be normal eyes):


Software Eyes:


Hardware Eyes (nothing changed except clicking F9):


Hardware Eyes:



The eyes in this game Jak 3 are dynamic and move using special processing (EE/Vu) I think.
Somehow using Hardware mode destroys the eyes behavior.
STRANGE?

I think the eyes should look in a direction of an object specified in the code, but somehow something corrupts this code and the eyes misbehave.
Sometimes one eye is black and the other is looking in the wrong direction.
Only in Hardware mode.

I think it also belongs in the Bug report thread because I suspect its not only a GSdx problem but also EE/Vu.

GSdx svn 5464.

Same problema with Jak and Daxter (Jak 1).

I pretty much ∟O∟"d @ the Hardware / software eye close UP comparison
