Microstutter at anything below 120hz

post #1 of 8
Thread Starter 
This is kind of long but please bare with me on this, i am desperate for help.


3770k@4.5ghz
6950 Crossfire
8 gig ram
win7 64

I have been getting what seems to be some kind of v sync microstuttering/frame skipping on some games. BFBC2, all Cods.. but not all.

here is a video of it happening
http://www.youtube.com/watch?v=sfioH6x1UQE


If i put my refresh rate at 120hz the ms/frame skipping goes away almost completely and the lower you go below 120hz, the worse it gets.

i prefer to play at 60hz because i use HDMI but the frame skipping makes it unplayable.

I had the same exact problem with BF3 but somehow using a frame limiter to 59.95 fixed that for me but it wont fix the others. I never had this problem about 2 years ago on the same cards. i've had to put up with it for that long as i only discovered 120hz makes it better.

some engines do it and some dont.

Disabling crossfire still makes it happen.

i tried turning off vsync @60hz on call of duty the microstutter goes away but horrible tearing.

tried bad company 2 and the stutter is still there a little bit but alot less then it was. Also the realy strange thing about this game is when i did a bit more testing with this problem and i entered a game with vsync off and using radeonpro's dynamic vsync,

all was well for about 5 seconds and then i notice the frame skipping slowly starts creeping back from light to heavy. I alt+esc to desktop then went back to the game only to find the frame skipping gone again, but then slowly crept back like before. this also happends if i toggle vsync on to off, stops at first then gradually gets worse over about 10 seconds.


i am on a acer GD245HQ.

crysis 2 still microstutters like mad but if i disable v sync in game and then turn on the fps limiter from bandicam the microstutter goes away but still has screen tearing. when i enabled v sync in game it comes back.

This does NOT happen in single player on BFBC2 but it does happen in COD MW2 single player.

sorry for the longness i try to explain the best i can.

Thanks.

well I cant see your video? anyway make sure that virtu is uninstalled & set v-sync to always on in ccc, check in CCC EDID is unchecked & set the refresh rate there? also if your using AA some games really don't like it in CFX?

how are you connecting to the monitor DVI/HDMI ?

cant think of anything else really, give that a try & report back?

Oh sorry. i have updated the post with the correct link.

I am connecting via HDMI as i need the sound from it and i also generally prefer the image it gives.

i only used DVI to test 120hz and discovered there is no skipping with it.

I'll give your advice a go and report back.

Thanks.

im not quite sure what you mean about the EDID?

Where/how do i go about unchecking it and setting refresh rate?

I dont know if this means anything but it says my max reported refresh rate is 75hz. is that right? i cant even select 75hz as an option.

actually EDID only shows up when analogue signals are used, doh?

you should be able to mess with the refresh rate in crontolpanel/display/advanced settings too though?

that's some bad stuttering too in the vid! my new card was doing it & I was nearly going stir crazy lol

there has to be something not set properly that's causing it? just try to find it lol.

Yeah i've tried pretty much anything and everything. Strange thing is it also happends on my other, completely different system which is XP dual core with a 5770.

i was lead to believe it was a internet problem, since most of the micro stuttering occurs in multiplayer and not single player.

i took my PC to a friends house down the road to test if it was my connection, but it still happend. I even changed providers to see if it would help but no. ran net tests and all come back ok.

when i use a 360 controller the stutter is not there oddly. only happends when moving the mouse and walking.

I'm stumped and guess i'll just have to live without playing a few games online frown.gif
