bought this system 6 months (from OCUK of course :)) ago but i am really confused as to what is wrong. it could be my EVGA GTX 295 or it could be my NEC 24WMXG3 monitor or it could be windows 7.

*the problem*

i have noticed it in two separate places the first is in games, Dawn of war2 in places has trouble with certain frames with quick moments, if you have played the game when the drop pods hits the ground at the start of the game the screen shakes. but I don't get a smooth shake I get a frame that is half / quarter drawn like a miss match of frames...this continues till the frame shake stops and the men get out. now this can't be low frame rate. in general where there is lots of motion this keeps happening

it also happens with Photo shop using CS4, I'm using the 3d acceleration option in PS to. this has the same issue again when i make a layer move things around quickly with the mouse and the object is almost jumping to the next place not moving smoothly like I would expect.

so i am not sure at all what's wrong, off the top of my head I'd say its not my 295 nor my monitor but windows 7, since installing 7 this has started happening really. but it could be coincidence.

so i ask / beg for some help on this i want my 2 grand set up to be flawless again. what could be the problem? please help its driving me mad.

running with driver version 196.21, windows update is on so updates install everyday or when they are released.
 
yeah crysis ran gr8 (on vista) not installed it since but fear that it would not be as good with the current problem. im gonna run Drive sweeper clear out the old driver and re install one of the older drivers above. and see if that helps. hope so. will let you know if this fixes it. thx for the help people :)
 
nope that has not helped at all. still the same :( installed the 195.64 drivers . anyone else have have any ideas what this could be?

Thx

i have now had a good hunt on the web for this type of problem, and from what i have read it seems that it is a 59HZ Refresh rate issue that is now present in Windows 7 with certain monitor displays. others with this problem report tearing in games to do with Vsync not being applaible in games as it need to be 60HZ.

mine is set to 59hz and when i try and set it to 60HZ it defaults back to 59HZ. basically this is screwing me over i think. others also mentioned that Nvidia will not sort this out and point the finger at Microsoft who call this a "feature" and not a problem.

well microsoft this is a problem a very real problem that means i cant now work in Photoshop since i upgraded to windows 7... thank you very much :(

if anyone can help me out here i'd appreciate it. i will keep looking. the only other solution is using a HDMI cable to my display. luckly my card has a HDMI from the card. will this degrade image quality? compared to DVI?

Paul :(
 
yes it is frustrating, i have tried this and i just get "this frequency is out of range!" my only option is try the HDMI cable or go back to vista or XP where is worked perfectly fine before i upgraded. i hate it when two big companies start bickering about a big problem. knowing full well that people have spent a small fortune on there setups. :(

Sucks!
 
well im not concerned with games that much tbh, its more of Photoshop that i have a problem with a tool i use everyday, for artists in the Games industry its an essential piece of kit :)
 
right its my monitor, little did I know that the NEC 24WMXG3 has a refresh rate of 8.8ms - 20ms on "Through Mode" and even more with it off 15ms - 30ms Average. even though its states its a gaming monitor at 6ms? while games are playable the full screen videos in these games with fast motion screen tear to hell. im learning allot of lessons with PCs these days same its costing a lot of money in the process.

i only hope that over the next year that Display Port really helps these response timing problems and that they become a thing of the past.
 
Hey thx Badger its working much better now. i did fix the tearing issue in photoshop at least by disabling the the V-sync option in the setting. however updating PS has given it so much power and speed, many thx. interesting how Adobe can't fix this gfx driver issue.

i am still unhappy with the "input lag" of my monitor, it ruins some aspects of gaming for me, maybe i am just being fussy? however, how would you find out what input lag a monitor has? and what is acceptable ? according to a popular monitor reviewing website the input lag for mine in through mode is 8.8ms. is input lag going to get any better in future?

on another note badge yes i'm pretty disappointed in dual GPUs as well, seems that not much is supported for it even now, and appears to cause more problems because of it than it actually solves IMHO.

anyway thx for your help at least PS is working gr8 now :)
