Most well known game engines

There is many games engine out there for game development and it's not a easy task to make own engine from zero. I will list most well known game engines.
Some people say that Scs Software need to change their game engine but this people or kids don't know anything about programming or optimization.  Scs Software have skilled programmers they have self created own Prism3D game engine that is optimized for truck games now some people say they should use Unreal Engine 4 that is a bad idea because Unreal Engine 4 is best suitable for shooter fps games and not for truck games. Also it is possible to make a truck game in UE4 but they must optimize it well. What Scs need to do is just update their Prism game engine to support DirectX11 & 12 and OpenGL in their recent interview Pavel said they will update their shader for Directx11.

Rig'n'Roll Gold Edition on Win10

Some people on Steam posted for Rig'n'Roll game that they had some difficulty to run the game under Windows 8 because of the protection StarForce, the developers do not want to update the protection driver to support Windows 8.1. You have to Go on the Steam Files, Rig N Roll, click on properties in rungame.exe, and take the compability on windows 8. it will run the game.

I have tested "Rig'n'Roll Gold Edition" DVD version 3.05.2726 and it works great under Windows 10 64bit "Rig'n'Roll Gold Edition" was released in 2013 by Polish publisher Cenega and it have not any protection and no StarForce. So if you want stay out of problem do not buy Steam version go for Gold Retail version.

This game could be great but developer ruin it, had some bad design and annoying long cut scene that you can not skip. Also the game map is based on real world distance and it takes very long time to deliver cargo and it make the game very boring and monotonous.


Rig'n'Roll Gold Edition includes Content Monster Cup add-on:
"The „Monster Cup“ is a special add-on to the Rig‘N‘Roll game, providing completely
new routes, vehicles, and allowing you to take part in a major truckers‘ race organized
by the CCWA (California Commercial Warehouse Alliance) In that competition, you not
only need to deliver your cargo - you also have to be the fastest driver! The Monster
Cup race consists of a few different parts and sometimes you just have to win a few
races in order to get to the next stage, but remember that in other cases even being
second won‘t be enough
The add-on is available either after finishing the Rig‘N‘Roll scenario or from the
„Story“ section in main menu, after turning that scenario off" info From Manual page 7

Vulkan (API) is OpenGL2 graphic cards

Vulkan (API) is next generation OpenGL in short you can call it OpenGL2.
The benefits with Vulkan and DirectX12 it will be faster and works closer to hardware.

To make the older graphic cards support Vulkan it is done by driver updates but some older graphic cards  will not be supported by Vulkan (API)
Nvidia and Khronos Group said  "we are not planning to support Geforce 400-500 class GPUs"

For AMD graphic cards to support AMD:s Vulkan (API) it need to be architecture Graphics Core Next (GCN), it means from Radeon HD 7000 and newer that will have support for Vulkan (API)

So in short Nvidia graphic cards from Kepler Geforce GTX 600-series and newer will support Vulkan (API) and if you have older graphic cards then it will not support it.
