I have a dual core opteron + 2gb ram, 7800gt's sli (I play at 1920 x 1200) and was actually playing with these settings last night. I definitely noticed a difference, mainly when fighting things in grassy areas. Previously I would drop to as low as 7 fps....with this plus all the other tweaks (including the MS xp hotfix for dual cores), I now maintain framerates mostly in the 20's sometimes even 30's when fighting in the grass.

Can someone repost that one here - I'm having trouble getting to the Elder Scrolls forums today. Thanks.

has anyone tried the "bAllow30Shaders"? This thread is getting humongous so didn't read trough it...

Anyhow, when I tried it, I got the feeling I was seeing alot more trees (too lazy to verify...) and I tought mayby there's geometry instancing going on. It's not included in SM2.0, right?

I tried it but didn't see any difference. I didn't compare screenshots though so maybe there is a difference and I just missed it.

Original Post

Modding these entries in the .ini file has gotten a significant perfomance increase for me. Im on a 3.2HT Pentium 4 with 3.0gb of RAM.

[OPENMP]
iThreads=10
iOpenMPLevel=10

iPreloadSizeLimit=1000000000

Someone else's comment (Wolfie's Den)

I have a P4-3.0 HT (o/c'd 3.2) with a passive Gigabyte 6800 (unlocked,355/800) and 3gig ram.

Oblivion was barely running on my system with most of the features disabled. Average framerate was only about 20-30fps in the wild, battle rates could be as low as 2-3fps (slideshow), market district bogged to as low as 5fps (near slideshow). Was very choppy. CPU usage averaged about 20% with rare spikes to 30%

After doing a bit of experimenting with the following settigs:
iPreloadSizeLimit=2000000000
iThreads=30
iOpenMPLevel=30

Also found and tweeked:
[GENERAL]
bUseThreadedBlood=1
bUseThreadedMorpher=1
bUseThreadedTempEffects=1
bUseThreadedParticleSystem=1

[HAVOK]
iNumHavokThreads=5

After the tweeks, Oblivion is running pretty smooth. Now my "in the wild" framerate is hovering around 50fps. Battle time is around 10-20fps (probably helped by turning on threaded blood and particles). Market district low side framerates are around 15-20 now. Way way better now. Only on very rare occasions does it get choppy now. I actually turned up the view distance with little degridation of the new framerates in the wild. CPU usage is up to around 60% with spikes to 70%.

I have a single core venice cpu. Personally i'd like to see some actual peformance charts and rgaphs before i start even playing with threads.

I'm not messing with this tweak. but if someone else wants to mess around with it and graph out the different settings and actual changes to their cpu usage as well as performance boosts thats relaiable and efficient, it would be nice.

Anyone knows what these settings actually do?

iThreads=10
iOpenMPLevel=10

iPreloadSizeLimit=1000000000

?

Has anyone figured out what the "Queued Count" in the debug display (console->'tdt') stands for. Is it the number of undrawn objects ? I noticed that when the value is high (and steadily decreasing), I see popups as more objects are drawn. If this is what it is, then it might be a useful tool to analyze the multithreaded tweaks.

No idea, but the developers are probably laughing their asses off sitting around reading the forums. Half of these probably dont even do anything but they make people think the game runs better.

Which is fine with me. If you can make me think the game runs better, then by all means, do it

Yeah. Someone (I nominate "not me") needs to figure out a way to run Oblivion in demo mode. It would make testing these tweaks so much easier and more consistent.

[killahsin]

but there is no consitancy the frames fluctuate unconsistantly even in a standing still mode. I think what we need is to wait for a few patches before we actually believe any form of benchmarking.

Thanks Christos. I played with those useThreaded ones last night and it did seem to put a little more processor load on - before I changed them I was running about 50-60% on one core and hardly anything on the other - maybe 10%. After changing those to 1 I saw about 50% on the second core also. Hard to tell though since the history graph on task manager is so short - anyone know a nice little program that will keep a processor load usage graph? Be interested to see just how much it takes advantage of dual cores.

When I've been doing to benchmark is:

1 - Load my saved game from immediately exiting the first dungeon. I then check what my FPS is before I even move. It started out around 35 before all tweaks. It is now at 42. I then walk in a straight line to a certain point and check the average (using fraps).

2 - Load a saved game that i have in a heavily grassy, lots of trees area where there's a wolf straight in front of me. I move backwards while swinging my sword at it.

Most of the tweaks posted yesterday and today have greated help my average fps in scenario #2.

I currently have no issues indoors or in most parts of cities.

I'm still awaiting my step up from EVGA, but for now the game went from barely playable at max, to very playable with my 7800 gt's.
