Low fps with 144hz?

I got the asus vg248qe and was playing black ops 2 with about 80-140fps. I cranked the refresh rate up to 144hz and now I get about 50-75fps. I didn't know the refresh rate effected performance(is it supposed to?) I thought it would just be fast enough the display the extra 30-90 frames that were going to waste in 60hz mode. Is there anything I can do to help the fps drop? I was looking forward to battlefield 4 because I ran the beta alright with 60hz but I want to play it with 144hz... Will a second 7970 enable me to max bf4 out with an above average frame rate in 144hz?

 


I don't use vsync. Same settings, same resolution, same hardware but when I increase the refresh rate my framerate drops dramatically in black ops 2
 


Maybe there is a setting in black ops 2 for refresh rate that I need to change, there was one in the first black ops. Like I said, none of my hardware has changed, all I changed was the refresh rate to 144hz and my fps dropped by about 40-50%

 
Have you tried another game? Increasing Mhz should increase smoothness but shouldn't decrease fps. It just allows your screen to display more frames than 60, but if you gpu has the potential to render more than 60 fps, it has nothing to do with decreasing the fps. Try another game and see results.
 


Seems to do the same thing on black ops 1 but not as dramatic, same with bioshock infinite. Left 4 dead 2 runs perfect but that game runs well on a calculator. Short answer, the fps drop seems to be applying to all games, as far as I can tell. Vertical refresh and triple buffering are turns off in catalyst. The next amd driver after mine are beta, should I try them? Are you sure it shouldn't be affecting frame rate?
 


I set it to 120hz and my framerate seems almost if not the same as before. I don't know what it is about 144hz but it makes me lag. Maybe it's a driver issue, or maybe even dual link DVI isn't enough for 144hz... I guess I'll keep trying it with every new driver that releases.

Edit: I spoke too soon, it helped a lot to turn it down to 120hz but it didn't fix it. stays around 100fps now but occasional drops occur that make aiming very difficult.
 


I'm up to date other than the optional updates.. Should I get those also? And by resetting cmos, you mean pull out the battery? Won't I lose all my settings?

Windows 7 ultimate 64
msi 970a-G46
FX-8350 cpu
8gb ddr3 1866mhz (2x4gb)
7970 reference card
ccc version 13.10
 
yes. lose your settings. something isn't running correctly. that's the reason for the cmos jump. ( read booklet. find jumper. jump. put jumper back to original spot ).

set monitor to 144 and leave it alone.


do you have the right BIOS installed to run that processor?


check your sound ( control panel sound ). if you are using on board sound make sure nothing else is enabled ( HDMI sound ).
 


I'm using the bios that came with the motherboard. I just did jumped the cmos and now where there used to be icons in my task tray, there is an empty space. two of them are still there in the exact place they were before. Also, in the sound section of device manager there is realtek audio, my headset and AMD high definition audio device. Disabling the AMD one didnt do anything. Any other ideas? I read somewhere that the frame drop when going to a higher refresh rate is normal...
 
kill the AMD stuff.................. do this.

disable windows automatic updates. also disable windows auto driver updates ( 2 different things ).

uninstall the AMD drivers from add/remove programs. reboot. reinstall AMD drivers but do a custom or advanced install. ONLY install the graphics driver ( the CCC also if you you want it ).

the icons in the tray. right click on the task bar. go to properties......... somewhere in there you will see something about showing icons. don't remember exactly what or how it's worded, but checking the box or un-checking the box will make the icons reappear.
 


I did all of the above, same frame rate... I'm starting to think there's nothing out of the normal and that you need more power for a higher refresh rate...
 
and there you have it......... if you have the hardware to push those frames then you will achieve them. buying a 144Hz monitor thinking you'll automatically get them is a fools errand. some newer games will get less than50, sometimes 30.......... even with better hardware than you have. ( intel build ) try some older games/earlier COD/MOH/Quake/Unreal3, etc. do the frames run high and steady?
 


Well everyone on other forums, such as this one: http://linustechtips.com/main/topic/63500-does-120hz-require-more-gpu-power/page-2#entry952000 are saying the refresh rate has nothing to do with performance, other than allowing a smoother experience. Because of this, I thought since I was getting such a high fps in 60hz that I would get that same fps in 144hz. Either there's something I'm doing wrong, or that's just not the case... Since you can control the refresh rate in windows, I guess it's not just the monitor in control of it. cod 4 is anywhere from 70fps to 130fps. How much do you think a second 7970 would help my cause?
 


Sooo is there a problem or not... The one I'm using now has different colored prongs than the one that came with my monitor. Both dual link but the one I'm using has copper colored ones while the brand new one has silver... It shouldn't matter unless we're talking about audio, right?
 


Without v-sync on, a monitor has no influence on FPS. With v-sync on, a higher refresh rate will only improve FPS if anything, unless you are using Adaptive Vsync (half refresh rate), which will cap you at half your refresh rate.

If you have less FPS, it is the machine, not the monitor or cable.
 




Ok I've heard this a thousand times, but that doesn't help at all. Why else would 60hz give me a better frame rate than 144hz? Even going down to 120hz gives a huge performance boost. What am I doing wrong? v-sync and opengl triple buffering are disabled in catalyst and obviously I don't have them on in game settings. Do you guys just not believe me?
 


Have you reinstalled your old 60hz monitor? The loss of FPS is almost certainly a coincidence when switching to a 120hz. Not a result of switching monitors.

The only other thing that pops into mind, other than settings differences, hardware issues, or temperature change due to HSF coming loose, is software changes. That might include the Lightboost hack.

Actually, with an AMD card, I have experience one other time that caused problems, and it wasn't really a FPS only issue, it flat caused a huge slow down of everything. Even at the desktop, but my monitor was flashing on and off. The problem I had was with a Displayport -> dual link DVI-D cable. It was having difficulties staying at 120hz, and the constant switching and blanking of the monitor would slow everything down.

Make sure your DL DVI-D cable is in the DL DVI-I connection on your video card. AMD cards only have 1 connection that is Dual Link. If that doesn't work, I'd suggest you consider RMA, assuming this is what you are experiencing.
