Y510p flickering/tearing in games

Hi all, hope someone can help.

Im having screen stuttering/tearing/flickering problems when playing any game on my y510p. This happens both in SLI or single card mode. I have windows 8.1 and all the latest drivers. I tried an older driver but nothing. I tried all possible settings in the Nvidia control panel (Adaptive Vsync, Sli rendering mode etc). Changed DPI (read somewhere that this could help), nothing. Im pissed off. I would appreciate any help or suggestions. I have no idea what to do. Everything else on the laptop is fine, just want to be able to play games normally. The frame rates in the games are good but its just the screen tearing/flickering. Basically you can see horizontal lines across the screen wehn moving around.

 

What are your temps?

 

Im getting about 84 deg for cpu and 76 deg gpu

 

What games are you playing?

 

Battlefield 3 and Metro 2033. I just noticed that the flickering is reduced whenever i turn antialising off in BF3. It remains in other games

 

Can anyone help? I still have horizontal tearing when playing games and even watching movies. Updated all drivers, tried adaptive vsync. Nothing helps!

 

Have you updated all the drivers from Lenovo's site? There is a fix for that on one of their video card drivers.

Your temps are fine, that shouldn't be the issue. Just make sure you go there and update all the drivers for your model.

 

Thx for the reply. I alrdy updated all drivers. I got the bios update for the second 750m. Sli is working so thats not the problem and I have the latest nvidia drivers. Dunno what else to do9

 

Explain the tearing to me. I am sure I can help you fix it. Post it here, I am going to bed in a minute, but I will respond first thing tomorrow morning.

 

I know you listed the temp for you CPU and GPU but which GPU temp did you provide? There are two GPUs and the Ultrabay one usually gets hotter than the internal one and if it is overheating then you could have issues.

 

Ok I will explain. Basically there are horizontal lines whenever there is movent in games or when playing videos. It looks like the screen is being sliced up.

Like this: http://upload.wikimedia.org/wikiped...(simulated).jpg/797px-Tearing_(simulated).jpg

Temperatures: GPU 1 - 75 deg, GPU 2 - 87deg

 

Well,

Install one of these and let me know how it does.

If you have the 755M then install

If you have the 750M then install

http://download.lenovo.com/consumer/mobiles/gt750m2ndvgayx10p.exe

 

I installed it but the problem remains

 

What about your power source. Is it the version with 170W?

 

Also try Unigine Heaven Benchmark. What kind of temps do you get (Sli and No SLI)? I will poste mine later in the evening.

 

If you are having issues after that and you have also updated your Nvidia video driver, then you have a bad GPU on the motherboard. I would just send it back for replacement. That is not normal and once you start seeing those lines, it is all downhill from there friend.

 

Hmm thats not good. I live outside the US so its gonna be a hassle. Going to see if I can open up the ultrabay, maybe try pop out and then reseat the gpu if its possible

 

I posted the temps. What you looking for with that benchmark, temps? Also its the 170w power supply

 

Sorry, I did not read your temps. I only want to know if you can see errors during this benchmark. I am running a SLI 750M by default (170W power source) since 2 weeks (german edition with 256GB SSD).
I can see nearly 90°C for the second GPU. 80°C for the main and the CPU has 20% load (using Unigine Heaven 4 Benchmark). But there is no flickering/tearing.

 

Ok. I overclocked the 750m core to 1193mhz with nvidia inspector and noticed a little less tearing but its still there. Are the GPUs supposed to have different voltages? GPU 0 reads 0.812V while GPU 1 reads 0.831V
