Mirror is displayed on the right side of the screen?Ok it's from buffered rendering ON,BR OFF fix it

[Donel]

Update on the emulation problems in this game:

- The fonts are all messed up
- When Buffered Rendering is On, the rear view mirror is broken and it seems to appear on the right side of the screen. When Buffered Rendering is Off, the rear view mirror works, but I'm not sure if the image it shows is accurate (it is different from the one showed on the right side of the screen when Buffered Rendering is On).
- The shaking caused by the Temporal AA only happens in some cameras. Maybe the internal framerate is lower than it should be in those cameras?
- Some visual effects are probably broken, as the game looks very empty
- The sound transitions as you change the camera are very abrupt. The music and the engines don't sound perfect to me, but I'm not quite sure.
- Vertex Cache lowers the performance a lot, contrary to other games, where it improves performance.

I'm just curious - is nobody else getting this?



The screenshot is from a recent build of v0.8, but any revision from the past couple weeks I've tried have had the same result. The track line guides draw, as do background elements, but most anything pertaining to the track is invisible.

This is on Windows 7 x64, with an AMD card (which I expect to be the problem, as it often is, with anything).

turn off mipmaping

Ah, yes. That does make quite the difference! Thank you!

v0.8.1
Well, after disabling Buffered Rendering, Vertex Cache, MipMaping and enabling Frame Skipping it gets pretty much playable, except for the unreadable text. Of course, it isn't smooth the whole time and some tracks have sections were the emulator start blinking with black interframes. Interestingly enough, the longer tracks (Nürburgring Nordschlaife and Circuit de la Sarthe) are the ones that worked better for me, having perfectly playable FPSs almost the whole lap. Also, the emulator doesn't seem to take all available resources (CPU and GPU don't reach 100%) with Gran Turismo, when I play Armored Core 3/SL/LR Portable or Whipeout Pulse it often does, just saying...

This game can get almost full fps when playing single race mode in several tracks like nurburgring or even time-trial and also drift event. FPS getting slow when playing in several tracks and even pretty worse, the FPS drops below 30. Hoping that the next update fixes some point that some decent PC hardware should able to run Gran Turismo at minimum hardware specs.

*Overclocking the GPU can help a bit, but overall it still not get a total full fps. After all, its graphic is totally like the GT4 PS2 game.

Where is the music? I miss the music

Anyway, this is awesome . Finally I can run it in PC at good frame rate.

I was wondering if the text problem is solvable. JPCSP had almost the same problem, and they "fixed" it, but it's still WAY too slow and glitchy to consider playable. PPSSPP is right the contrary. Is there hope seeing this fixed or is too soon to ask?

[amirzaim]

Ok...i have a problem when the autosave text is appeared, and then it crashes even it shows the black screen during the game starts. How to fix this? This problem happened after I'm playing previous game in the emulator.

In 0.8.1-401 the rear view mirror now displays properly:


Two issues still remain though:
-Mipmapping still causes those horribly broken texture graphics
-In-game text is still rendered incorrectly.

[Donel]

Update 2:

- Some stutter in the intro movie.
- Mipmapping breaks in-game textures. This also happens with other games and will be improved when the mipmapping implementation gets better. That's what henrik said.

- Screen shaking caused by the Temporal AA.

Vertex cache slowing things down: this isn't a bug or issue, unfortunately. What it means is that they are changing constantly, so the overhead of trying to cache them is just wasting time.

I wonder if the text is related to mipmapping or something. So weird.
