GTX 295 - HUGE input lag in crysis and tf2 HEEEELP!!

I have watercooled my new GTX 295 so warranty is void and no chance of taking it back. its overclocked to 675/1200.

I have now tried crysis warhead demo, and tf2 and both behave identically. i move the mouse around and about half a second later, the character on the screen moves. its rendered the games COMPLETELY unplayable. I was using a 8800GTX before and never ever had anything like this, movement was instant.

it isnt a framereate issue, tf2 is running rock solid 59fps and never budges an inch. it is driving me absolutely mad after only 5 mins.

i have now suddenly seen loads of posts about micro stuttering (no idea what it is yet) and lag using sli. surely to god a £350 graphics card is not rendered completely useless when playing games because the input lag is so ridiculous you cant play it properly?

driver version i have according to device manager (windows 7 RC) is 8.15.11.8618 dated 10th june 2009.

anyone able to shed any light on how i might fix this?
 
TF2 is more CPU dependant though? so it's leading me to believe that you have a slight bottleneck in your system?

Specs?
 
correct vsync was on and turning it off seems to have solved it (just discovered that after i posted). BUT i turned it on to solve the problem of having a band scrolling up the screen all the time which was driving me mad.

i have a HP LP2475W, I7 at 4.2ghz, 6gb at 1600mhz.

so it seems the lag was caused by vsync but without vsync i have this stupid band moving up the screen. i also notice that the refresh rate in nvidia control panel is always saying 59. i can change it to 60 but then as soon as i go back in there, its on 59 again!!! i am guessing maybe something to do with this is causing the band? the monitor itself says its running a 60 when i go to information but i guess it may be running at 59.5 and rounding it up or something. i have no idea whats going on, never had this with my old 8800

no i cant see it in there.

it did the same thing with my old 8800gtx though windows control panel always saying 59, change it to 60 and go back in and its on 59 again, and i didnt have any scrolling band on the screen with the old card. its obviously not a bad card cos the band isnt there with vsync on. GAH!!

its an lcd, this one doesnt run at 75 only has options for 59 and 60!! (i have another that does but its an old small one). i dont even know why 59 is in the list.

Its prolly 59.8 or something.

This could be a problem - I usually run games at 100+ fps so that these tearing artifacts aren't noticeable (except on highly specific areas) as having vsync on does horrid things to input latency, especially badly on SLI. But if you can't get the fps high enough it might not be possible to reduce it without vsync... in which case you'd have to reduce pre-render frames to 0 or 1 to even get close to a less laggy feel which would negate the whole purpose of having SLI as performance would drop back to almost single card :(
 
Lol, soo many people disable vSync it's not always though of :p.

Could the scrolling line be to do with the internal SLi of the card? I.e each GPU takes half of the screen, causing the line?

Look around in the NV panel to see if you can disable internal SLI and see if it goes.
 
no the line is a band about half inch thick that scrolls from the bottom of the screen to the top then starts again from the bottom.

is this card faulty or what? cos an old 8800 had no problems like this

i have the fps set at 60 to sync it with the netcode but thats really not the issue. i dont pay huge money for the fastest card out there to put up with this sort of crap! shouldnt matter what fps i run it at there shouldnt be strange corrupt bar scrolling up the screen!

yeah i think i saw 59.8 somewhere, but i cant remember where i saw it now!

i just disabled SLI and its still there. i also tried it on my other monitor and its there on that as well so it isnt monitor specific

Your gonna have to lift the fps cap... if its a game that hard caps to 60 your kinda screwed (most aside from doom3 this can easily be done in config files tho).

This will happen with any GPU with vsync off and a framerate thats close to the refresh rate but without being locked to it.
 
if thats the case can you explain to me how i have never in 15 years of fps games experienced this before? and how ive had my 8800gtx capped to 60fps on the 60fps monitor for over a year and not seen a single line accross the screen?

im running exactly the same fps on this card as was capped on the old card so unless something is wrong, id surely get the same NO bands on the screen as i had before. i have never run vsync so if that was an issue id have seen it surely?

to have horizontal bands scrolling up the screen just because the monitor fps is close to the games fps is ridiculous in this day and age let alone on the most powerful card you can buy and on a high end 24" lcd.

i have removed the fps cap completely and just let it fly about between 400 and 150 and i THINK the line is still there but its very hard to tell. that doesnt really solve the issue though, sooner or later ill be running games that cant be run at 100+fps even on this card, so they would have ot be capped around 60, you are saying i going to be stuck with this problem again then? crysis warhead might be such a game already, even without fps being capped if it happens to hover around the 60 level im going to be stuck with this again?? ive never heard of this before now.

I had the same issue with that card in a lot of games.
i was not keen of this card at all.
So got a single 275, which is now sorted. also play with v sync on :)
my mate has 2 x 275 sli of course, with no issues. :) i'm going to get 2nd one my self.. i play 1920x1200
 
TBH I'd say you probably had vsync on before - for some reason the input latency caused by it is amplified by SLI - even if your syncing at a silly high framerate... also it depends on the timing of the switch to drawing the new frame and the screen banking - on some configurations you just never notice it.

Tho it does sound more pronounced than usual so its possible the GPU or monitor is faulty - but personally I'd say both were fine.
 
well if it turns out to be a specific issue with this card then im not ever going near nvidia cards again.

i have NEVER had vsync on, not even in the quake 1 beta. always wanted the high fps.
