→Emulation issues
Several problems occur when running PS1 games, and they become more noticeable at resolutions higher than native internal resolution when using plugins which can increase it like Edgbla's GpuBladesoft, Pete's OpenGL2 and GSDX. Though they're still apparent at native, the low resolution's aliasing and blurriness kills almost any visibility, hiding the issues.
Jittering polygons are caused by low-precision fixed-point (to the native res, essentially) math. And more accurate math where relevant helps, i.e. [[Recommended_PSX_Plugins#Video|GTE Accuracy]]. Though it can often create holes in the seams. It also should be possible to implement more precise texturing.
The PS1 hardware didn't have a [https://en.wikipedia.org/wiki/Z-buffering z-buffer]. The lack of a z-buffer causes things like polygons popping over others. Tekken character limbs are a good example to see that.Its theoretically possible to implement Z-Buffer in PSX emulators/GPU plugins.[http://translate.google.com/translate?depth=1&hl=en&ie=UTF8&prev=_t&rurl=translate.google.pl&sl=ru&tl=en&u=http://forum.emu-russia.net/viewtopic.php%3Fp%3D17237]
