Set the internal resolution to a multiple of native (e.g., 2x, 3x). Never use a custom resolution like 1920x1080 directly, as it breaks alignment in many PS2 games. The GSdx 11 plugin's upscaling routines are optimized for multipliers.
To understand GSDX 11, you have to look at what came before it. In the early days of PS2 emulation, the Graphics Synthesizer (the PS2’s GPU) was a nightmare to emulate. The architecture relied heavily on massive bandwidth and specialized blending modes that PC GPUs simply didn't support natively. Pcsx2 Gsdx 11 Plugin
Early plugins relied on "Software Rendering"—using the computer’s CPU to draw the graphics pixel-by-pixel. It was accurate, but brutally slow. Set the internal resolution to a multiple of native (e
GSDX 11 was part of the wave that shifted the burden to the "Hardware Rendering" capabilities of modern GPUs. By utilizing Microsoft’s Direct3D 11 API, the plugin allowed the PC’s graphics card to handle the heavy lifting of upscaling, texture filtering, and shader complexity. It effectively bridged the gap between the fixed-function pipeline of 2000s console hardware and the programmable shaders of modern PCs. To understand GSDX 11, you have to look
GSdx is a graphics plugin (GS stands for Graphic Synthesizer, the name of the PS2's GPU). Unlike older plugins that relied on software rendering (using the CPU), GSdx utilizes your PC's Graphics Processing Unit (GPU) via hardware acceleration.
GSdx 11 specifically refers to the plugin variant that utilizes the DirectX 11 (D3D11) API.
The GSdx 11 plugin supports external shader files. Look for GSdx.fx in your PCSX2 shaders folder. You can enable:
