Could you post a log file at INFO level and a profiler output? This might give some hints about the performance issue...

Have you tried to not select "Disable optimised VertexInfo reading (may improve compatibility)" and to select "Use vertex cache"?

"Use vertex cache" no help, still solw as it was.

and "Disable optimised VertexInfo reading (may improve compatibility)" will be a speed up setting if "Use vertex cache" not select.
That settings is for NVIDIA play Gundam vs Gundam Next PLUS. I am sorry about forget change before test this game.
BTW, some of my friend using AMD graphics card, they can't find a good settings which can may JPCSP run Gundam vs Gundam Next PLUS at full speed.

From the profiler:

Code:
Texture load count: 4786, average 5.8 per GE list

There seems to be quite an usual high number of texture loading per frame. This could explain the poor performance in some screens.
When reaching a slow screen (e.g. with FPS=5), could you enable the log level to DEBUG for a short time (2-3 seconds should be enough) and post the log file?

Thank you!

Hmmm, not a single frame has been captured in the DEBUG log... could you try to let it run a bit longer?

Thank you!

OK, now one frame is available Smile

The game seems to reload the same texture with different cluts (only changing the clut start parameter):

Code:
44:31 DEBUG       ge - GUI - sceGuClutMode(cpsm=3(PSM_8888), shift=0, mask=0xff, start=3)

44:31 DEBUG       ge - GUI - tflush 0x089EAA20, buffer_width=512 (512,512)

44:31 DEBUG       ge - GUI - tflush texture_storage=0x4(PSM_4BIT_INDEXED), tex_clut_mode=0x3, tex_clut_addr=0x089EA620, texture_swizzle=true

...

44:34 DEBUG       ge - GUI - sceGuClutMode(cpsm=3(PSM_8888), shift=0, mask=0xff, start=15)

44:34 DEBUG       ge - GUI - tflush 0x089EAA20, buffer_width=512 (512,512)

44:34 DEBUG       ge - GUI - tflush texture_storage=0x4(PSM_4BIT_INDEXED), tex_clut_mode=0x3, tex_clut_addr=0x089EA620, texture_swizzle=true

This is causing a texture reload at each time. I will improve the texture caching for this situation.

The texture cache has been improved in 3e2aa29. Does it help to improve the performance?

think you, now it run in normal speed.

Great news!

Now the number of texture loads looks normal:

Code:
Texture load count: 98, average 0.0 per GE list
