Jerky performance
   

Got some funky stuff happening here…I got an AMD 2500+ the other day to help increase the performance of G2. I was using 1.1g and it ran OK accept for the city and all I had to do was knock down the view dist. for an acceptable play. Now here is where it gets weird, after installing the 2500+ (OCed to 2.2g) I started G2 leaving all configs the same. My last save was in the city and when it loaded I noticed right away the game was running smooth with VD set at 300…I was gathering my crew and started to head to the lighthouse to recruit the old sea dog for the voyage. As soon as I got past the city gates the game got very jerky. I scaled back on VD…no change so I scaled back on OF form 300 to 100…no change. I turned around and went back into the city and it started to fly. I went back out the gate and it got jerky again. WTF…? I decided to exit out of G2 and scale back on FSAA from 4XS to 4X. Restarted the game and I got the same results. Why would the performance of G2 reverse itself with the addition of a faster processor? I checked the FR and in the city it was 19-22. When I entered a house it jumped to 33-37. Outside the city it was 14-17. Another thing that strange was when I started to enter the pass to the ship it got jerky again and smoothed out when I got to the dock. It's very jerky in the grotto also. I am almost tempted to reinstall the AMD 1.1.

Can you try running some benchmarks in windows, on your new cpu. Post them so we can see if thats what a AMD2500 should be like.

Also try running a demo/benchmark of another 3D game and tell us what results you get

I can download some BMing software off the net but after contemplating this issue for a while I am starting to think this might be a graphic card issue. Prior to the 2500+, the 1.1g CPU probably did not have the HP to crunch the data fast enough in the city to run smooth and the GF4 was fast enough to handle what the CPU gave it. Even in woods the bottle neck was still the CPU but since data was not as intense as the city the CPU & GF4 could handle the info with acceptable performance. But now with faster CPU the GF4 is choking outside the city where the graphical info far surpasses anything in the city. But I may be wrong about this…

I had kind of the same thought…but not as drastic as a reinstall. I saved my ini file then turned on the recalc switch in the ini file, started G2 and ran the intro and loaded my last save. The game smoothed out quite a bit after that…the grotto ran a little jerky around the torches but once past them it ran OK. I have not checked to see if the performance has increased in the woods yet though. I quite the game and compared the two ini files and the only diff was that the intro set VD & OF to 100. I could see no other changes to the file. So I started the back up and jacked the VD & OF back up to 300 and loaded. The game ran the same…so what ever it is; it’s not affected by changes to VD & OF. I wish I knew wtf the recalc was doing because it sure as hell isn’t in the ini file.

I’ll bet it makes its changes in the reg…the one thing I didn’t bkup.

so, at the end of the day, were you able to achieve an across-the-board perf. increase with your new CPU?

The city definitely runs smooth with VD & OF maxed now…something I was never able to achieve. As for the country side, I will load an save and check it out. Since the Grotto smoothed out after the recalc I should get a better performance in country. I did see a perf hit last night in the fog…also something I had not seen before…One more thing I’m seeing is a shining star formation at some spawning points in the puzzle temple after they are killed.

I rarely experienced something very similar to what you explained. It has something to do with the sound. When you leave the city gates the sound changes and there are a lot more effects. That is generally when the fan speeds up and he CD might start spinning. The choppiness might be the result of the sound. If you've got sufficient memory, the sound is probably a contributing factor.

I think that is normal. I also saw what you describe. They are probably just magic portals the evil magicians created to spawn or provide a pathway for evil to enter through. The evil eventually stops coming through those tiny portals... I'm pretty sure they are supposed to be there.

Thanks for the pointer…I did a lot of experimentation last night with FSAA and the ini file and nothing I did fixed the problem. I did not think about the sound as a factor. It definitely is not a hardware issue. I tuned on frate last night while I played and also checked out some old saves. I averaged 23fps in the city, 18 in country and 43 in houses. Hell, I even got 74fps in the grotto where the dragon waits, but I also got extreme jerkiness in parts of grotto also and they all are around where the torches and camp fire are. I was leaning more to the visual part i.e. the flames but the sound makes prefect sense. Something with the crackle of the camp fires & torches are having a negative impact on the game…I’m going to jack up the sound cache in the ini and see what happens. I’ll let you know the results of my findings. Funny PB never chimed in on this…

Weil jacking up the sound cashe didn't help...

zTexCacheOutTimeMSec=480000
zTexCacheSizeMaxBytes=64000000
zSndCacheOutTimeMSec=20000
zSndCacheSizeMaxBytes=40000000


I'm back to the graphical thing...when I walk through the shinning stars my frps dropped to 8...

Do you think my GF4 Ti 4200 64mb DDR card is the problem? I"m running a 2g CPU and 1g 333 DDR RAM

At first I was puzzled by your seemingly low FPS rates... but then you mentioned that you play at 1024 and you use FSAA and stuff like that, so its probably normal. also its impossible to have a true "average" framerate for the country, it varies too much. AND of course we all use different view distance, that has a big impact.

also:

"One more thing I’m seeing is a shining star formation at some spawning points in the puzzle temple after they are killed"

I think thats a bug in the game, that affects everyone. basically the way i see it, if you can get through the whole puzzle temple segment WITHOUT saving/reloading, you will never see the star formation.

the moment you start saving/re-loading those star formations happen.

don't know why.


also, not to criticize your new card or anything, but i heard that particular model was not so good. something about it being actually slower than a Geforce 3 Ti 500 or something.

Actually I play at 1280x1024x32 w/FSAA at 4x and the frates in the countryside range from 14 to 23. I am aware that the GF4 Ti4200 is not the best but the fact still remains…the jerky performance did not start until I installed the faster CPU, I can not for the life of me figure out why going to a faster CPU would make the game stutter.
