Slowdown Issues with Chrono Cross?

[Paladin0228]

I've been playing Chrono Cross on ePSXe 1.5.2 and during the status screen/menu I get kind of a lag effect, and the music slows down noticeably.

Also during battles while performing attacks, sometimes I will get a random jerk/slowdown for a few seconds...

Was wondering if there were any suggestions for this.

what video drivers are you using?

May sound dumb but I'm not sure where to look to find this..

Driver Version : 6.14.11.6218 ??

for the Nvidia Geforce 7300 GT

Upgrade to newer drivers, go to Nvidia's site.

Although I think this is the solution to your problem.

I am running what seems to be the newest drivers for my card.

open GL2 is a graphics card hog right, try switching plugins to see if the results vary widely

I have tried :

Pete's OpenGL 1.76
Pete's DX6 D3D 1.76
Pete's D3D 1.76
Peops Soft Driver 1.17

I could not find settings tolerable to run the game.

While I could find settings that made the game/music run somewhat smoother, I always would have choppy/unreadable text issues which is why i stuck with the GL2 despite the problem I am having.

its doesn't even use opengl 2 , it can though, if you use one of the shader modifiers

The slowdown you noticed in battles is usually due to framebuffer effects. Framebuffer effects are very cpu demanding. So there are actually two things you can do:

a) Lower the framebuffer uploads/effects settings of the plugins.
b) Lowering the internal x,y resolution settings of the plugin helps a lot also, if you want to keep your framebuffer effects settings as they are, not missing the effects.

FBE's in this plugin are done via the GPU, so they are actually GPU and memory bandwidth dependant rather then CPU dependant.

his cpu is perfectly fine, his video card just suffers from having a 128 (possibly even 64) bit memory bus.

10GB/s... that explains it all,.. thats around the performance of a Geforce 5600... for fullspeed FBE you need 20GB/s+

Compatibility:
- Offscreen drawing: 2
- Framebuffer effects: 3
- Framebuffer uploads: 1

try reducing these settings one number each.

[Squall-Leonhart]

offscreen drawing should be set at 1, and framebuffer uploads on 2 or 1

[Paladin0228]

battles somewhat better squall..

music in menu screen still slows down badly..

Oh well ^_^

Thanks for the help!

[Squall-Leonhart]

turn off/down screen filtering, the menu is rendered as a FBE and filtering FBE's can cause slowdowns on weaker video cards, and remove the shader effect, or lower the shader level

i would think removing the shader effect would do the job though.

[hushypushy]

Try messing with the texture filtering options. Some wreak havoc on the menus.

[Linktothepast]

I prefer using hi shader level without texture filtering, since it usually causes more trouble than it's worth. Give it a try.
