Graphical Artifact (GTX 760)

Akrura · Aug 8, 2016

Hello! A few day ago i have noticed that i have some graphical artifact (little white pixels).

This happens only on some textures. Every time they are placed randomly. Also saw this in GTA V, but i find temporal solution: alt+enter, move window and back to fullscreen. Other games like Wolfenstein The New Order, MGS V and etc. works perfectly. I have latest NVIDIA Driver (368.81,GTX 760,Win10 x64, PSU 700w) and i also not overclocked my GPU. GPU temp is ok. I'm try to delete driver and install again, but it doesn't help. I'm try to reinstall Windows and nothing. Any solutions?

The white flickering on textures is generally the GPU struggling to render properly, usually because of overclocking. You mention you haven't overclocked the GPU, however you may have the in game settings too high for the card to handle certain types of texture rendering. This might not be putting a strain on the card in terms of heat, but it may be pushing it too hard in terms of available resources and the bandwidth available on the card. The GTX 760 is a capable GPU, however it is only a 2gb card and is starting to show its age when forced to run newer games which generally recommend 4gb video memory.
My suggestion would be to reduce some settings in game (eg, MSAA/FXAA/Anisotropic filtering levels etc) to see if these reduce the screen tearing/white flickering. If not, you may need to underclock your graphics card. As mentioned you haven't overclocked it, however they come out of the factory with a "Should be fine" overclock pre-assigned to them. Depending on your GTX 760 version, it may be pushed 100mhz or so higher than the stock/reference version of the cards. As such, you might want to try lowering the base clock settings for these particular games to see if it helps.

I'm not sure that CS:GO needs 4 GB of VRAM

Sometimes it happens, sometimes is not [pixels]. Also i find temporal solution: alt+enter, move window and back to fullscreen

CS:GO may not require 4gb video memory, but it does have graphical options for MultiSample Anti-Aliasing, Texture Filtering, FXAA Anti-Aliasing, V-Sync etc.
Certain cards perform better with certain types of anti-aliasing. Do you have MSAA enabled with FXAA? If so, you are running two types of Anti-Aliasing which are likely to conflict in some cases (eg, FXAA is a low level filter and is unnecessary if you are running MSAA, which utilises the GPU more).
Do you have V-Sync enabled? If so, you may see screen tearing and artifacts because the GPU has pre-buffered frames which are then displayed overlapping, due to the delayed response from your monitor. Disabling this option may also increase your input lag so may help with CS:GO.
Do you have MSAA set to 8x? If so, this may be too high for your card, as previously mentioned, it's not particularly high-end and is the lower end of the GTX 7xx range. Considering your card was released around the same time as CS:GO, it is fair to assume that it may struggle with the higher end graphical processing settings. Even if you feel CS:GO is not as graphically advanced as MGS:V which you mentioned runs fine, they are very different games, made by different companies. The textures may not be compressed as efficiently, the shaders and memory allocation will function differently. Unfortunately you cannot assume an older game will work as well as a new game, especially when the GPU drivers tend to focus on tweaking performance specifically for these newer games.

I saw pixels in GTA V (after CS:GO problem), this never happened before. I play this game from original PC release (license) with same settings. And here i find solution: settings -> graphics -> refresh rate (original 60Hz) -> set lower (pixels disappear) -> set lower (pixels shows again) -> back to 60 Hz (pixels disappear).
