Ok I have just recently upgraded my Oblivion game with the new Qarl Texture Pack 3 and since I have installed it my system doesn't seem to be able to handle the game at all, I've had to drop AA and AF down to 2 and even now its struggling at times, my FPS have dropped quite considerably because of the high-detail textures its now having to deal with.

Is this my GPU, RAM, CPU? What is it down to?

Spec is as follows:

E6600 @ Stock
GeIL PC6400 2GB
BFG 8800 GTS 320MB
Antec Truepower Trio 550W
 
They are all strong components, what mobo have you got? Try overclocking you processor, you can whack that one right up to 3gig at least.
 
Got an Abit AB9 Pro, been saying it for weeks but I'm going to be overclocking soon just haven't had the chance to sit down and do it and ensure its stable because of work and things.

Temps @ load:

CPU: 38-40C
GPU: 55C
 
Resolution is 1280, everythings on full. Before I installed this pack I was running AAx4 AFx4 HDR the lot and FPS was fine, it was very smooth. Now its choppy!
 
As far as I can see theres no reason it should be running slow at that res on your system, try reinstalling the game and see, if not full reinstall maybe in order
 
How big is the texture pack, seems a bit far fetched, but if your actually exceeding the 320mb of memory on the graphics card, then performance will be dire, as is starts swapping textures in and out of system ram.
 
Could be that the textures are filling up the 320MB memory on your GTS, though at 1280 I think it's unlikely.

What kind of FPS are you getting now?
 
Turned off both AA and AF and gameplay improves, still lacking in places though. So would it be video memory thats being utilised here and not my GeIL?
 
Put the AF back up, and try again. I have a feeling it is only the AA is hitting the fps.

The system RAM should also be utilised, as there are hardly any gfx cards with 1GB of video RAM, which is the amount of space taken up by the Oblivion textures.
 
sounds like the memory of your GTS is being pushed, even tho its a 1gb texture pack, surely its not likely it can display all 1gb of textures all at once in one particular area?
 
You dont need to keep every texture in graphics memory all the time, the game will swap in the required ones as needed. However obviously the more memory on the graphics card the less often the game will have to swap textures from system ram, to the graphics card.

Graphics card ram is lightening quick, while system ram, and the PCI express bus are snails by comparison.

Enabling AA uses up a great deal of additional graphics memory just for the framebuffer, pushing even more textures out into slow system ram.

AF on the other hand shouldnt have a big hit, as its more processing rather than memory driven.

In the old detonator drivers it used to be possible to get a chart showing how much of the cards memory was in use, and how much system ram was being reserved for graphics too, Perhaps there is some current application which can do the same thing?
 
I dont have the pack yet as i gave up trying to get it as the download rate was appaling, but i would say its probably the 320mb on the GTS being the weak link, that packs gona take a huge amount of vram, also to see what the fame-rates like, Fraps is your friend.

Im still going to attempt downloading it so ill let you know how it fares for me when i eventaully get it, but as i said the 320mb looks likely.
