This is the answer i got from Wargaming world of tanks game developers
Thank you for contacting us.
We are sorry to hear about this issue. Unfortunately Intel graphics are not fully supported in World of Tanks and such problems are indeed possible. It seems that the driver you are using suffers from a memory leak every now and then. At the same point, the Intel drivers are known to have various issues in the DirectX11 mode, including for example artefacts.
Therefore, we recommend you downloading the file from the link below into your game directory and using it to launch the game instead of the game launcher:
This will start the game in the DirectX9 mode, which is considered a "compatibility mode".
Don't hesitate to contact us again in case of any further issues.
Thank you for contacting Intel Communities.
When you have a custom made PC, you have the opportunity to customize settings in the BIOS such as shared memory, as you mentioned up to 50% of the RAM; however, since you have an OEM system, some features or customizations are not allowed or blocked by the OEM; therefore, assigning 50% of the memory may not be possible
In this case, you can try installing the Intel® Graphics Driver Beta [15.45] driver to see if the problem goes away.
You can also check the recommended settings for this game at gameplay.intel.com, you will find specifications for a different processor but the graphics controller is the same (Intel® HD Graphics 530) and the specifications are pretty similar.
You can also check the answer given by the game developer as it seems that it is a known issue that they are aware of.
Please don't hesitate in replying to this post if you need further assistance.
Hi, thanks for reply.
i will start with a picture
as we can see as i have mentioned before i have intel HD 530. So shared graphics memory is limited by OS. Here we have how it is done Calculating Graphics Memory (Windows Drivers)
here is my system outputs
So max memory theoreticly can be used as video memory up to 8GB. OK lets say to get that much might be will be hard so lets go down by half to 4GB it can be easily shared as video memory and this should be more then enough to play without errors i have mentioned.
I don't like to use beta driver version as have to disable driver sign enforcement and loosing security (secure boot).
Game settings? Ok i'm playing with lower settings provided by link you gave me.
Anyway thanks for reply again i will keep trying to investigate and eliminate the problem.
You are right, 4GB should be enough, seems to be a random issue as you mentioned you are able to play the game for hours without any issues.
Please let me know if you are able to implement the solution provided by the game developer.
I can implement solution provided by game developer but all what they want me to play with direct x9 and this will decrees my graphics visual . Graphics wont be as much nice as it is with direct x 11.
I think that problem is with bad game ( maps ) optimization as I don't have such a problem with any other game.
problem was drivers updated drivers with new release no more problems.
