Weird Frame Rate Problem With GeForce FX7600 GT SLI

by Jackie Hayes · in Torque Game Engine · 06/11/2006 (10:56 am) · 18 replies

Hey Guys...

Has anyone ran into this problem... I have built a new dev system with almost everything I thought I would need. It is an AMD 4400 X2 with 2 Gig of Ram, GeForce FX7600 GT SLI and the AGEIA PhysX Processor. I am using a modified version of 1.3 with the lighting kit. When I enter any level the frame rate runs about 10 to 20 FPS for about 20 to 30 seconds or more, depending on how many objects I have in the scene, then jumps up close to 200 FPS and runs fine after that. I have update the Mother Board to the latest BIOS and have updated the GeForce and AGEIA boards with the latest updates. I do not have this problem on my other dev machine which is allot smaller.

Does anyone have any idea what may be going on at startup?

Thanks for any input.....

Is the scene jumpy? If it is, there are so many threads on this already

@SphyxGames

The scene is not jumpy but, as expected, when the frame rate is 10 to 20 FPS the mouse movement and scene is choppy until the frame rate increases then it is normal. I also found that this only happens when you start the game and enter a level for the first time. If you drop out of that level and go back into it or go to another level, without restarting the game, the frame rate seems to be normal at 150 - 200 FPS. I am going to try and dig into it some more tonight.

Thanks for replying!

I have the same problem but with my GeForce 7900GTX. Just started recently.

System Specs:
AMD 64 x2 4400+
2gb PC3200 Ram
Sata 7200rpm 160/80 drives
GeForce 7900gtx

I'm guessing it's a thread problem. I'll be looking into it later once I get some more GUI stuff done... I hate GUI's.

Whew....I'm glad I'm not the only one having this problem with new equipment. Thought I might have set something up wrong. I am trying to dig into this also. If I come across anything I'll post it here.

Thanks Matt for letting me know you are having similar problems...:)

I thought it might be the dual-core thing you were discribing. I get no problems on a 7800GS

Hmm..I am still checking into this. Still have the problem though. It might be the dual core processor but when I play Ghost Recon Advanced War Fighter it works fine. I thought it might be the Ageia PhysX board because I have not implemited the code for it yet but Matt seems to be having the same proplem and did not indicate he has the Ageia PhysX board. When I fiqure out what is causing this I'll let everyone know.

Let me force the exe to one thread and see if the problem goes away.

Yeah, it's daul core related.

Interesting Matt. I wonder how we are going to get around this in code. I am sure more and more people are going to run into this in the future. Maybe there is a way to detect this on start up and force it to one thread or find a way to take advantage of the technology. I'll keep digging also.

Thanks!

Well the first thing I am going to test if it is related with the tick methods as they create weird lag with deticated servers, if that doesn't seem to be the problem I have no idea how to fix it in code.

I am going to look at it this evening. Maybe someone from GG might have an idea. Seems like it is going to have to be fixed one way or another to make TGE compatable for newer equipment...ie dual core processors. I'll post back when/if I find a resolution.

Thanks Matt and everyone else for your input!

Folks,

Any update on this? We jsut ran into the same problem. One of the member has exactly the same dual core system as mine however he runs it with one monitor while I have 2 connected. He runs it without problem. The card is GeForce 7600GT

Thank you

Vic

The only thing I can attribute to this is the dual core. I switched to just one monitor and still have the problem. I have been busy on work related issues so I have not had allot of time to dig into this. As soon as I can find something out I will post it here.

If anyone else has this figured out please let everyone else know.

Thanks!

The problem is with the dual core. You need to download driver updates and apply a hotfix for your processor to fix the problem. I run a system with an AMD X2 3800 and GeForce 7600GT SLI and have had zero problems after the installing the udpate.

Scott,

I'm on an Intel mobo with Pentium CPU. Do you mean to download the hotfix for the CPU or the mobo?

Thank you SO much good to know we are not alone :)

I can't say for absolute certain since I'm not running an Intel system, but it would most likely be for the CPU as that's what it was for on the AMD processors. The best place to check first for the fix would probably Intel's site.

We're definitely not alone. There have been numerous threads about this ever since the dual-core processors came out. Its not just an issues with Torque either. I've had the same problem with other games as well.

I could not find a hotfix for the CPU (if anyone running Intel CPU had any luck, please post), however I found this:
http://support.microsoft.com/?id=896256

Did anyone try this?

Thanks

Solution for Intel users:

In the BIOS set "Max CPUID Value Limit" = "Enabled" It solved our problem and as I can see MS is aware of the problem and planning to fix it http://support.microsoft.com/?id=896256

Good luck to you all
