I'm using epsxe 2.0.5, and Pete's Opengl2 2.9 It appears the floor is smoothed, but the walls are still pixelated, and unchanged. It seems that the floor is 3d, while the walls must be 2d which could be the reason why the pixels aren't smoothed. My Settings for Pete's Opengl2 2.9 are here. Full screen mode - On Desktop Resolution - 1024x768 Color Depth - 32bit Internal X resolution - 2 very high Internal Y resolution 3 ultra high Stretch mode - 0 Stretch to full window size (standard) Render mode - 2 use frame buffer object (fastest mode, if supported) Texture Filtering - 6 Extended + smoothed sprites Hi Res textures - 0 None (standard) gfx card vram - 512 Off screen drawing - 1 Standard Frame buffer effects - 2 Standard Frame buffer upload - 2 Full Screen Filtering - On Shader Effects _ Glslang files (AA shader 4.0 + colors) Shader level - More (Walls are still pixelated on any of those settings, even on maximum) Scanlines - Off Mdec filter - On Here are some screenshots Is there some sort of extension or extra setting that smooths out 2d in a 3d game? I even used Pete's Opengl2 tweaks which uses xBRZ scaler, but the walls are still the same. They have no more glitches on them when using that extension, but the walls still have pixels. There must be a fix for this, or a type of texture filter made just for 2d in a 3d game. Extended + smoothed sprites makes the floors, and polygons smooth, but the walls are still the same, and unchanged. Any help is greatly appreciated. Thanks.
