I hope you don't mind a very long post.\r\n\r\nSpyro 1, Software mode, 1x resolution, 2x window scale shows a **large black bar to the right side** of the screen.\r\n![retroarch 2016-10-08 16-05-41-228](https://cloud.githubusercontent.com/assets/8392067/19218080/56883390-8db5-11e6-93bb-054634e2e550.png)\r\n\r\nSpyro 1, Software mode, 2x resolution, 1x window scale shows a **green line at the bottom of the screen and a large black bar to the right side** of the screen.\r\n![retroarch 2016-10-08 16-06-11-978](https://cloud.githubusercontent.com/assets/8392067/19218326/77cef7bc-8dbc-11e6-9725-f09312d30ab7.png)\r\n\r\nSpyro 1, GL mode, 1x resolution, 1x window scale looks good except **the brightness/gamma is shifted brighter** than the Software mode. It's subtle, but noticeable if you flip back and forth between two screenshots.\r\n![retroarch 2016-10-08 16-08-00-901](https://cloud.githubusercontent.com/assets/8392067/19218337/c05eb954-8dbc-11e6-8be3-b999251c93fb.png)\r\n\r\nSpyro 2, Software mode, 2x resolution, 1x window scale shows a **colored line at the bottom and right side** of the screen.\r\n![retroarch 2016-10-08 18-24-07-617](https://cloud.githubusercontent.com/assets/8392067/19218376/d0e032fc-8dbd-11e6-9795-1a5ba0438f86.png)\r\n\r\nSpyro 3, Software mode, 2x resolution, 1x window scale shows a **colored line at the bottom and right side** of the screen.\r\n![retroarch 2016-10-08 18-29-43-362](https://cloud.githubusercontent.com/assets/8392067/19218381/ef278be8-8dbd-11e6-8cab-2d222ed856ee.png)\r\n\r\nTekken 3, GL mode, 1x resolution, 1x window scale shows **character faces are obscured by darkness** and will occasionally flicker with the normal texture appearance.\r\n![retroarch 2016-10-08 18-36-50-358](https://cloud.githubusercontent.com/assets/8392067/19218413/01d6cf50-8dbf-11e6-9d74-ea1ee5548c9d.png)\r\n\r\nOpening cutscene has a **double-image and the bottom half flickers**.\r\n![tekken 3 cutscene](https://cloud.githubusercontent.com/assets/8392067/19218436/75286fea-8dbf-11e6-9b33-e9b96de0dd6b.png)\r\n\r\nEnabling the new PGXP mode via memory only sometimes causes patches of the **ground textures to get corrupted**. Strangely, these textures get fixed if you load this scene from a save state. This is also a good time to point out that GL mode seems to **shift textures out of place** (in all games, not just Tekken 3), causing visible seams where there should be none. The skybox is a good example of this.\r\n![retroarch 2016-10-08 18-52-51-563](https://cloud.githubusercontent.com/assets/8392067/19218463/14f98e64-8dc0-11e6-8731-9e2db3c6f3cf.png)\r\n\r\nPGXP memory + CPU **causes polygons to warp out of place** when characters are pushed beyond the border of the screen. One of the **character's textures also go crazy due** to PGXP (in both memory only and memory + CPU).\r\n![tekken memory cpu](https://cloud.githubusercontent.com/assets/8392067/19218464/2fdefe94-8dc0-11e6-8d54-d4009ae4b150.png)\r\n\r\nThere also seems to be some kind of **large square particle artifact** after getting hit in the game.\r\n![tekken particle artifact](https://cloud.githubusercontent.com/assets/8392067/19218498/083f7728-8dc1-11e6-8dc0-2016ef15c5f2.png)\r\n\r\nPGXP memory only, and texture perspective correction enabled **causes textures to go missing entirely**.\r\n![invisible eddie](https://cloud.githubusercontent.com/assets/8392067/19218537/18bffbb2-8dc2-11e6-98bc-e8899330fb49.png)\r\n\r\n\r\nLet me know which of these error examples need full VRAM images to accompany them, I forgot to grab those earlier."}}
