The higher resolution has almost no speed impact when plugin renders the picture (because the picture is actually resized to this resolution from the '''internal resolution'''). | ||

** '''Software renderer''' -- uses your CPU to render the picture. There will be ONLY native internal resolution available (thus poor looking visuals). But in cases of some games this mode gives much more correct picture fixing many GFX related artifacts. Unfortunately GSDX requires much CPU power to render with software renderer even in internal resolution (without anti-aliasing or anything else applied) so you may end up with 3-10fps unplayable but correctly rendered game (some games are rendered quite fast though). Note also that PCSX2 is very CPU hungry but currently supports only 2 cores (the third core may also help a wee when used by different system processes leaving first two exclusively to PCSX2) thus if you have 3 or 4 core CPU you may consider using them for GSDX working in this mode increasing the render speed dramatically with every additional core (see '''SW renderer threads'''). | ** '''Software renderer''' -- uses your CPU to render the picture.

* '''D3D internal resolution''' -- is used to set the render resolution target. The higher resolution you choose here the bigger picture will be rendered before being resized into your screen resolution thus you'll see more clear and crisp visuals. Unfortunately all those game you'll be playing were created and tested for lower native resolution (~500 x ~450) so some picture parts or objects may look wrong (displaced/framed/no image/invalid colors, etc.) when rendered in higher resolution. These artifacts you may eliminate only by using '''native resolution'''. Increasing internal resolution will impact the rendering speed so the higher resolution you'll set the more powerful graphics card you'll need to have. | * '''D3D internal resolution''' -- is used to set the render resolution target.

In contrast with higher (in most cases) '''D3D internal resolution''' is more compatible mode but suffers from poor visuals. This is the native PS2 mode you'll see picture this way when you're playing on the real PS2. Use it when you cannot play in hi-res because of unbearable artifacts. You can also switch between the two in runtime, see '''List of ingame keys'''-'''F9'''. | ||

Every additional thread here means one additional CPU core will be used in the rendering process. You're still going to need at least one core left for the PCSX2 itself so if you, for instance, have 4 cores (quad core CPU) you may want to set this field to 3. | ||

It's an attempt to gain additional speed while transferring 8-bit textures and have more free space in video memory. May or may not have some positive impact for some cards with some games. | ||
* '''Alfa correction (FBA)''' -- is a correction to make some textures partly or fully transparent (as required by the emulation) but may cause unusual slowness in some games.
