Game can NOT be randered correctly on my computer

You are correct. It's that 128mg intel video card. 

The games minimum specs are: 3D Video Card w/2GB VRAM (Nvidia GeForce 950 / AMD Radeon RX 450)

Oh no, there is 8GB Shared menory, and I'm pretty sure the GPU on i5-1135G7 can run this game (see The Performance of the GPU in i5-1135G7) . This is a bug, not the lack of performace.

Dude, you're trying to run a brand-new game on an on-board intel GPU, sorry mate, but it simply won't work.

That won't work. Intel reports that as "shared memory" because it's taking memory from the OS to pretend like its video memory. We need the minimum specs I listed above. At least 2GB of dedicated video memory (Nvidia GeForce 950 / AMD Radeon RX 450).

It is definitely a bug if this game can only use the dedicated memory. The current NEW GPU from CPU (or APU by AMD, like 6800U) and OS memory are definitely fast enough to run this game.

And, it is definitely used the shared memory form my test, the occupation of shared memory has arised from 1.6GB to 3.0GB when game is started. So it is just the rendering bug, not the lack of performace.

Well first of all, you use a mobile processor and they are not really made for gaming and 4 core falls into the minimum requirement for the game.

You also have an integraded graphic card who share memory with the rest of the system.

A detail of the minimal requirement

The RX450 is:

512 Shading Units

32 Textures Mapping Units

16 Render Output Units

The GTX 950 is:

768 Shading Units

48 Textures Mapping Units

32 Render Output Units

Your integrated graphic card has only 80 Shading Units.

From intel Doc :

The Execution Units (EUs) are the programmable shader units of the Gen Architecture. Each is a standalone programmable computational unit used for execution of 3D shaders and media/gpgpu kernels. Internally each is capable of multi-issue SIMD execution, and their hardware multi-threaded operation provides a very high-efficiency execution environment in the face of long data latencies typically associated with memory accesses. Each hardware thread within and EU has a dedicated large-capacity high-bandwidth register file (GRF) and associated independent thread-state. Execution is multi-issue per clock to pipelines capable of integer, single and double precision floating point operations, SIMD branch capability, logical operations, transcendental operations, and other miscellaneous operations. Communication to support units (shared functions) for operations such as texture sampling or scatter/gather load/stores is via ‘messages’ programmatically constructed and ‘sent’ to those functions, with dependency hardware causing the issuing thread to sleep until the requested data has been returned.

And since these units also have to make the textures mapping and the rendering...

To me your card doesnt meet the minimal requirement.

This only shows that you don't have enough knowledge about this GPU.

First, the number of "Shading Units" and "Execution Units" cannot be directly compared, because they are defined differently and have different performance.

In summary, you can see the approximate performance of this GPU from this link, and for reference, the time spy score of this GPU is roughly 1279, compared to 1193 for the RX 550 and 1912 for the GTX 950.

It's coming from an intel document, not from me...

Dude, it's not going to work.

You have two options at this point, use a different desktop PC with a video card or play something else.

It's not a bug, it's your machine, stop blaming the Devlopment team.

I've been in IT for over 30 years, there is no bloody way you are going to get a Surface Pro to play this game, it is not what the Surface Pro was designed to do. Best to have another rig to play games on, my son has a Surface Pro and an Acer Laptop for gaming.
