PROBLEMS:

I have searched and read through all the forum trying to find a solution to the following problems but had no luck :( (I found some stuff but it didn't work for me)

First of all I would like to know if I have to switch between NTSC and PAL depending on the image I'm using or should I just leave it on autodetect?

Secondly both sound and image jitter in all the video secuences (in every game). It does it in a very specific way. If I turn off "frame skipping" I get less jitters but after a few seconds the number of jitters increases and by the end of the secuence it's awfull :mad:

In Chrono Trigger the music speeds up and down when you change from one room to another, when you go to the inventory page, when you get out of a village to access the world map,etc... (basically, in loading times)
(note: when I play Chrono Trigger I use the P.E.Op.S Soft Driver 1.16)

Thank you in advance guys :bow:

PS: Is great to remember old times. I'm playing Tomb Raider, WipeOut 2097, Resident Evil and all those great games from this lovely console :) ePSXe ROCKS! :guitar:

Leave it on Autodetect.

Use OpenGL1.x. The 5xxx series aren't really best with OpenGL2.x, and leave frameskipping off. Also use the full Eternal plugin rather than Lite

Does this happen if you use ePSXe 1.5.2?

What do you mean? Im using OpenGL Driver 1.75. Which one should I use insted?

If I leave frameskipping off the music in most games speeds up and slows down. Is that supposed to happen?

Thanks a lot for your help mate! Very cool the Full version of Eternal (reverb rules :D)

PS: I have also tried with pete's D3D driver 1.75 and it seems to work fine except for some stuff (weird lines apear across the screen sometimes, mainly in video secuences) The music doesn't speed up when I use this driver and the video secuences run perfect (except for those weird lines that I have just metioned) oO What is happening :???:

--------------------------------------------------------------

Well, when I turn off frame skipping the videos run fine with both open GL and D3D drivers but as I said, the music speeds up and slows down in most games (gran turismo 2, ridge racer 4, chrono trigger, etc)

They are the latest drivers

EDITED:

I think I've found out the problem. I tried to play Chrono trigger with the P.E.Op.S. Soft Driver 1.16 with this setup:


Resolution/Color:
- 800x600 Fullscreen - [32 Bit]
Stretch mode: 2 (stretch to window size, keep aspect ratio)
Dither mode: 2

Framerate:
- FPS limit: on
- Frame skipping: on
- FPS limit: Auto

Misc:
- Scanlines: disabled
- Game fixes: off [00000000]
-------------------------------------------------------

The frame rate was perfect (59.9 all the time). Then I played it with the same setup except for the stretch mode which I choosed 3 this time (2x Sal stretching) and the frames started to drop out from 59.9 to 40 all the time oO I've got enough CPU to handle that so I guess it is some sort of incompatibility with HT Intel technology? Hopefully not...
______________________________________________
EDITED:

It looks that I'm having problems with performace. When I turn the OpenGL driver settings to "FAST" (with frame limit on) then I the games run perfect but they look crappy (sound is stable due to the fact that the frame rate is stable)

The thing is that I think my computer is "strong" enough to run those games with the best quality. Don't you think so?

:hdbash: :hdbash: :hdbash:

EDITED:

I found the problem... it has to do with the texture filtering. As soon as I use the 5th or the 6th type of filter (smoothed sprites) I get a drop out in frames. I can play with the rest of the settings and set them up into max and the frame rate will still be stable. I can't believe my computer can't run that properly with hi-quality settings. There has to be something wrong. I mean, I can't believe that I can play Half Life 2 at 800*600 with great quality but I can't run an old playstation game with some filtering.

I'm playing in a very powerful laptop (Alienware Area 51-m). My processor doesn't save energy unless you are using batteries.

PS: As I said before, I can play Half Life 2 quite well with full graphics at 800*600

I think I've heard of high texture filtering options causing slowdowns before but I don't think it's very common. I suppose every computer is different; for instance if I set the async mode in Eternal to Smooth, I get framerate drops every few seconds, yet it's fine if I set it to Simple. Try putting the texture filtering setting back up to the level that was causing problems then change some other settings, like setting hi-res textures to 0, dropping framebuffer texture to 0 and raising framebuffer access to 4, dropping offscreen drawing to 2, etc. I just tried your current OpenGL settings on my PC (used windowed mode instead of fullscreen :p) and I was having slight framerate problems (drops to 50-55 FPS every few seconds) so my guess is is that the combinations of settings is putting too much of a load on your system.

Edit: I forgot I underclocked my video card to 93/697 when I first tried those settings :heh:. After I set it back to stock speeds, the severity of the framerate drops lessened. It usually only dropped down to 59 from 59.9, which makes me more convinced that your video card can't quite handle those settings
