Is there a framerate cap on Oblivion's Engine?

[TheLotusEater725]

Here are my Rig specs

EVGA 780i SLI

Intel QX6700 OCED to 3.4 ghz

EVGA GTX285 Superclocked

Gskill DDR2-800 8gb's

Two western Digital Raptors (not in raid although)

4 250 gb WD caviar.

Dual Acer 22" 1680x1050 Monitors ( i turn one off through the driver panel when gaming)

 

 

So yesterday i got my brand spanking new GTX 285 and decided to bring up the ol' TDT command . Now i know even with a Core i7 proc and mobo people have only gotten about 80 fps with the Fallout3 version of the Gamebryo engine but even then they were running at way higher resolutions than my monitors run at. Now obviously i took into account that maybe my proccessor mobo and RAM were showing their age but it didn't make sense since with my 8800gtx and my proc and RAM running at stock speeds i was getting about 55 frames per second. So i said "what the hell

" and I overclocked my cpu from 3.ghz to 3.5 and clocked my GPU Core clock from 675 mhz to 685 adjusting the shaders and memory accordingly. My RAM sticks were running at 1066 mhz but they weren't stable at that speed so i set them back to their stock speed of 800mhz. Again i couldn't get one frame past 60 fps.

So i decided to run Oblivion with all sliders down to 0% and at 800x 600 resolution turned off all Anti-aliasing and filterings...i still couldn't get past 60 FPS. So my fellow Elder Trolls, any idea what is going on here? The most i can figure is that my RAM/MOBO/CPU are bottle necking the system. I know 60 FPS is more than acceptable considering i am hitting it even with all my settings maxed out even when the driver is forcing AA/Anisotropic filters and all other image quality improvements.

Did you try playing Oblivion with mods? If yes, some of them might eating up resources on CPU/RAM level. I doubt that with your sys-specs, the graphic settings really matter.

Oblivion's problem with performance isn't exactly the visual quality, but the scripts running all the time. For the few days I played FO3, I never noticed lags or slowdowns even though my PC's a granny compared to yours. I guess that Beth changed the script management of it so it's not dragging down your performance so much.

 

Ah yes, now that I think of it, I remember another case: one guy, having a high-end rig experienced quite heavy slowdowns. In the end it turned out to be his onboard soundchip causing that. He installed his old soundcard and recieved a major performance boost. Could be that same applies to you, in that case, deactivate the music and check if it's still running so slow.

This may be a monitor issue. If the monitor cannot display more than 60 fps, that's all you get. Try changing the monitor frequency and see what happens - like from 60hz to 50hz. Some monitors allow 70 or even 80hz.

Having V-sync on will also lock your maximum frame limit if you have it on and the framerate is dependent then on the refresh rate of your monitor. You can turn it off if you'd wish in the options menu of the Oblivion launcher I believe. Plus, Fallout 3 probably is going to run better than Oblivion, because despite being a newer game, because less is going on in Fallout 3 than in Oblivion.

Correct information, just to add a bit more on information, V-sync will round down to 30fps if the fps falls under 60 on refresh rate of 60, for instance. Because of this, v-sync must be disabled on almost all games, unless absolutely necessary. I suggest you doing so in the vcard driver too, and in some games you may need disabling it in the ini file.

 

Another approach to allow v-sync when the clipping is severe enough to justify it is using the triple buffering, I read somewhere than doing so is tricky under DirectX. The tweakguides site is a good starting point to resolve performance issues.

 

Although the OP points for the above answer, MaYuYang have a point here too, Even with that rig of yours, having the onboard sound card will create the most frustrating experience since the fps fall and heavy stuttering is not depending on graphical issues in this case. Yet, even with a good discrete sound card using the Quiet feet mod is a must. That last suggestion is because there is a bug with the creatures paws noise that only totally disabling them will help.

 

PS: with yours machine pushing down the graphics slides and resolution will help nothing. If you have 'graphical' issues (indeed, any performance issues) with it, the better is seeking for a guilt elsewhere, things often overlooked as heavly fragmented files on the HD (mainly the MFT), messed Windows register and so on.

Well, thanks for all your help guys, it saved me from pulling out my hair in confusion. So i turned off V sync and JESUS OCELOT CHRIST! My frame rates on all the Valve games i have skyrocketed to 100+FPS and on Oblivion i am getting no less than 65 FPS. As far as Oblivion gos my biggest performance killer is my hard disk. On Fallout i am getting an average of 70 fps as well. Thank you all VERY VERY VERY much.

I also have the same problem

 

Computer specs

Intel Quad Core 2.4gz

8800gt 512

4gb of RAM of Kingston

Nvidia 680i SLI LT Mother Board

 

Before i switch my RAM, because of a bad RAM, I got great fps 60fps always in caves and at a, minimum outside 40fps, it was so wierd i tryed defraging my hard drive, cleaning my registry, rolling back and updating my G card. The bad RAM i had talked about corrupted a windows file which i repaired, could that be the cause, i talked with technical assistant and he said the RAM i have is compatible so whats going on then, also fallout 3 has the same problem.
