I'm not sure why you would expect a CPU-limited title (using CPU-limited settings) to perform better with a GPU upgrade... I've played KOTOR on my X1650XT @ 1280x1024 w/all settings maxed and it ran fantastically. This would've been last year on a 7-series driver.

Until you got outside in Taris city and it slowed right down.

I didn't see any difference when I completely upgrade my computer recently. Sure, Kotor is not going to be using both cores of my new CPU, but a single core of my 6400+ is still 1ghz faster than my old 3500+ was.

I think we aren't a million miles away from agreement anyway, I get the impression that you know the default OpenGL performance is not great, but you are happy with the fact they can fix it, and to be honest so am I as far as gaming is concerned, but I would still like the performance bringing up to an acceptable level for my other interests.
 
Fair enough Andy. Seems to me that most OGL games nowadays (at least the ones people play) are in fact D3-engine titles, however.

What driver(s) were you using? I didn't experience slowdowns at any point during gameplay.
 
I've only had the one ATI card to this date so yeah.

I wasn't really into PC gaming before and just used my PC for internet and office stuff and the occasional game on kotor as I didn't have an xbox.
 
Perhaps a silly question but were you running an NV card in that system prior to installing the ATi card, and if so, did you reload Windows?

Not to spin it anymore but it is a CPU mather. Myself ran it fluid 1024*768 4xAA/8xAF @max on a 9600XT and Athlon "2500+" CPU, both KOTOR games. It smoked my Geforce4ti4200.
 
that was a known problem with kotor and ati cards (you had to put the atiogl.dll froman earlier set of drivers in the game folder to as a work around) anyway i beleive its been fixed for a long time now

So basically DJ12 needs to run DriverCleaner (at the very least) or re-load.

No, only the ATI card has been in this PC.

When I upgrade my CPU, memory and motherboard I also fitted a new HDD so started from scratch.

Trying out kotor was one of the first things I did too when everything was running as it was why I upgraded in the first place. It was my goal to achieve 60fps in the outside upper city section in Taris, sadly it failed.

As you wish...

3DM06 fillrate - single

HD4850: ~ 7300
HD3870: ~ 6500

Interesting that there's been an increase in fillrate despite a decrease in clockspeed and no increase in execution unit count. I'm assuming no AA was in-use here, so this can only mean Z-fill has increased as expected.

There's a bug in KOTOR where ATI cards (as well as newer Nvidia cards ironically) had horrible performance in certain areas.

You had to change a line in the an ini file to fix that:

Disable Vertex Buffer Objects" option in "swkotor.ini": [Graphics Options] Disable Vertex Buffer Objects=1

I disagree. Single texture fillrate usually is nothing more than a memory bandwidth test. So it's interesting to see this score increased for hd4850 over hd3870 - just the same as it did in vantage it seems (and I'm going to stick to the better color buffer compression theory for now...)
 
mczak, I certainly can't disprove your theory at this point in time, but I doubt the inclusion of any new compression scheme would provide the results we're seeing at this point in the life of GPU design. IOW: all the low-hanging fruit in this area has already been picked. It would take a radical new paradigm to achieve results like this, and I just don't think that would've been possible during the design phase of RV770.

Ahem. OpenGL most certainly is not designed for gaming - pretty sure it predates 3d gaming cards... Now newer extensions certainly are useful for games, but there's nothing inherently "designed for gaming" there.
(sorry for OT)

OGL in the desktop space most certainly is meant for gaming, however, so in this context I am correct. If we were discussing development in a workstation environment you would be correct.
