GPU Usage Drops When Using Fraps

post #1 of 4
Thread Starter 
Not sure if this is the right section for this but I am having an issue which I really think I shouldn't be. I believe my specs are listed below but if not the gpu is gtx680 in sli and cpu is 3930k at 3.3. When I play skyrim on the highest settings plus mods I can easily get almost 200fps in some areas. I actually have to use msi ab to lock the fps at about 90 because of skyrims mechanics. Water flickering, banging noises, ect... Anyways I have been recording videos on youtube for awhile now and been using fraps with no issues. I decide to make a skyrim lp series and notice the second I hit record my gpu usage on both cards drops to 50% or less. I have msi ab set to see my stats on screen. The fps drops to like 30-20fps which is just unplayable for me. Any other game I have no issues. I have the newest build of fraps set at full screen 60 fps. The same settings I have been using for awhile now. I had the newest drivers but rolled back to 314.22 with a minor increase plus because of all the issues with the new driver. I just don't understand why gpu usage would drop more than half when recording. I am lost at this point and I don't know what to do. Any help is appreciated.

Thanks

1. What resolution are recording at
2. how fast are your hard drives?

This is the limiting factor for me and recording on my system.
A single 7200RPM 6gps sata3 hard drive is not suitable above 1600x900(actually that's pushingit, you'd need to step down to 720P to maintain 60FPS at that bitrate), you either need an SSD or a Raid 0(sata3) pair of hard drives for recording.
The higher resolutions and the lower write speeds cause write and throttling limitations.
which leads to 3.
3. fraps forced frame limitations, if you're going above 60 average and then you turn on fraps to record its going to force limitations.

If you want to record and have the SATA 3 ports open for it, pick up a pair of 7200RPM 6gbs drives and raid 0 them together and use them for recording or drop some cash on a high capasitiy SSD to record with.

My gaming monitor sits a 2160x1215 and I can not record above 15~20FPS, however when I use half size it will record about 40~50FPS.

Recording at 1920x1080,and the drive is 7200rpm. I have recorded every game with the same exact settings with no issues. I tried recording to my samsung 840 pro and the same happens. I tried my intel ssd and still the same. Just played for about 2 hours but this time I set fraps to record at 80 fps. Haha, huge as files but it did maintain a little better. Stayed around 50fps or so even sometimes to 60. I got a copy of dxtory and it records a little bit better but the gpu usage drops as soon as I hit the record. No recording they both max out at 99% with plenty of fps to spare. I don't lock the framerate in fraps and the split movie every 4 gigs is unchecked so it's one big file. I will try half screen and see how it does.

Thanks

For anyone out there I am bringing this thread back up. I have bought 2 WD 10EZEX 1 TB drives and have set them up in a raid 0. I am still not able to record at 60fps at full screen. I don't know what to do now. I went to the fraps forum to see if they knew and after doing all the tests they needed, there reply was " lower your recording fps". If anyone knows please help me. Thanks
