Oblivion runs poorly with good gpu

GPU: 6755g2 (6620G & 6750M dual graphics)
CPU: A8-3500M
I read on the website review of 6755g2 that older games aren't accelerated and performance can depend on driver support. I don't know what this means or what I can do but I believe that it may be what is causing my performance problems in oblivion it really becomes laggy when I'm talking to an npc and when there are a lot of npcs on screen. Is there anything I can do or would I have to buy a different computer to play oblivion?

I believe that's the game engine's fault. It doesn't handle tons of NPCs well. If you mean in the normal game, then yeah it may be a driver issue, but if mods are putting huge amounts of guys on the screen... There's only so much it can take.

 

Do you have any mods installed?

My understanding is that Oblivion has a problem where it crashes if it exceeds 2GB RAM usage. This can be alleviated by the use of a couple of utility mods, like Unofficial Oblivion Patch, Unofficial Shivering Isles Patch, Oblivion Crash Prevention System, Oblivion Stutter Remover, Streamline, and the Large Address Aware NTCore 4GB .exe patcher.

If you already have some mods installed the crashing could be caused by your mod load order, or a conflict. Try using BOSS and/or Wrye Bash to resolve these problems.

At any rate, most of us who have played Oblivion a lot of hours have dealt with crashes - save often and it helps if you have an SSD, so you can load the game again faster. In general, it's a much less stable game than Skyrim.

As for lag when there are a lot of NPCs on the screen, that would seem to be more related to your CPU than your GPU. Also perhaps your asymmetrical crossfire is not kicking in for some reason, so it might only be using your 6620G integrated graphics or the 6750m. You might want to post on the sub-forum related to your specific laptop model to see if others have a similar problem.

 

It boils down to Oblivion is poorly coded - it has to handle a lot of AI/NPC activity and only really makes use of one CPU thread for the bulk of its work. I just played through the game a couple months ago and my 4 ghz 2500k dropped to 30-40 fps when there were a lot of NPCs/heavy combat going on, and one processor core would be pegged at 100%. Unfortunately, there's not a lot you can do about it. Lowering the actor distance and changing distantgridcount to 3 in Oblivion.ini should help, but it won't eliminate lag with a a lot of NPCs in close proximity.

Your GPU is not the problem; I was able to run the game maxed out at 8x AA on a 5730, and the only slowdowns were directly related to the CPU. No matter how complex the landscape, if there was no one or only a few people nearby, I got 60 fps.

Since you have a Llano APU, have you tried overclockcing? I believe HTWingnut made a great guide on it, and your CPU is completely unlocked so its very easy to do. Most people can get to 2.2-2.5 ghz very easy on them.

 

All you need for Oblivion to run smoothly on your machine is an SSD upgrade. Once you install Oblivion on the SSD everything will run smoothly without the otherwise constant jitter.

The way the game works is by constantly loading data from the hard drive the game is installed on, and if you get a decent SSD read and write times are going to be many times greater than the ones on your current hard drive.

experience. Installed Oblivion on my SSD last year and it ran as smooth as butter maxed on my Sig Laptop.

 

Skyrim runs better than Oblivion with better graphics, just saying.

 

This might be true for the vanilla game, but if you have a lot of mods it is still going to be a bit unstable, even with SSD, and graphics mods or mods that add lots of NPCs can slow down the frame rate significantly.

Even though I have dual Intel SSDs in Raid0, after installing Qarl's texture pack, Better Cities, Unique Landscapes, FCOM, OBSE, Oblivion Graphics Extender, etc., I still had a lot of framerate fluctuation and the game crashed at least once or twice per gaming session. Without any mods I had constant 60fps.

 

Really weird but some of the performance issues I've had no longer are happening such as lag when talking with an NPC and simply walking around it was really bad, unplayable. The only issue I'm having now is lag when I'm close to more than one NPC even two can bring my fps to less than 20 but when im walking around its pretty smooth I can even turn on 8 Anti-Aliasing and everything.

 

Nyllod, i wonder if you were using integrated graphics before? Can you force the 6750m to run in CCC for oblivion? in alienware, we can type FN+F7 and choose dedicated graphics to force dedicated graphics

 

I'm sure it was using dual graphics when I was lagging before, I really don't know what happened unless I somehow forced it by accident.

 

I have never played a TES game in Vanilla form although I did not use the Quarls Texture pack at the time. I did use better cities, UL, fcom, obse, and OOO along with many others I can't remember and the game ran extremely smooth.

 

I'm playing vanilla oblivion no mods I go down to 10-20 fps when I'm exploring and when I'm in combat or with some NPCs on screen. By the way would overclocking the CPU help and how would I do that?

 

At what resolution?

Even at 1080p, you definitely shouldn't be getting 10 fps with no mods and 6620G + 6750M. This game is more than 6 years old. I had constant 60 fps at 1080p with no mods and my GPU is a bit slower than your setup.

I'm guessing there is something wrong with your drivers and the asymmetrical crossfire, or perhaps only your integrated graphics is kicking in for some reason.
