Polygons may jitter as a result of low-precision, fixed-point (to the native resolution) math, but this is mostly unnoticeable at native resolutions. Emulators that can increase the internal resolution of games have attempted to fix this.
There is no [[wikipedia:Z-buffering|z-buffer]] in the hardware. This can cause things like polygons to pop over others; the limbs of [https://en.wikipedia.org/wiki/Tekken_(video_game) Tekken] characters are a good example of this. It is theoretically possible to implement this, but it wouldn't be accurate to the hardware.<ref name="forum.emu-russia">{{cite web|url=https://translate.google.com/translate?sl=ru&tl=en&u=http://forum.emu-russia.net/viewtopic.php?p=17237|title=Plugin info, news. / Information about the plugin, news.

When perspective correction isn't applied to textures, certain viewing angles can make them distorted, more so when an object is near the edge of the camera up close. [https://en.wikipedia.org/wiki/Tenchu:_Stealth_Assassins ''Tenchu: Stealth Assassins''] is particularly infamous for texture distortion, most noticeably in the [https://www.youtube.com/watch?v=5oBeO-cui_c training level] where floor textures appear wavy at oblique angles; developers usually mitigate this by adding polygons to walls, floors and other scenery, but at the cost of filling the PlayStation's geometry rate. In DuckStation, at least, this problem has been solved.
