The upgrading of the 9.9 graphics World of Tanks has undergone serious modernization. We updated the image smoothing methods, significantly reworked the shadows, improved lighting and optimized performance of the game client. Also, great attention was paid to the overall stability of the image – now you’ll see less “flicker” in various post-effects (HDR Bloom, HBAO, RO, etc. D.).

This article tells of the change and will demonstrate qualitative growth “pictures”

New anti-aliasing

In version 9.9 of the game, a new method of anti-aliasing – temporal smoothing TSSAA (Temporal Super Sampling Anti-Aliasing).

Smoothing (Anti-Aliasing) – Technology used to eliminate the effect of “jaggies” that occurs at the edges of objects.

Among the technologies highlighted smoothing TSSAA excellent quality and the general image stabilization eliminates the visual noise of pixel jitter on thin objects and flickering shiny surfaces in motion.

In contrast to the existing World of Tanks in the method of smoothing FXAA, TSSAA – it is a high temporal method that is used to smooth, not only the current frame, but also has a certain amount are drawn to this point shots, with the reconstruction of the old pixel position using their velocity. This allows for a smoother, more cinematic images in the game with little additional load on the graphics card.

Unlike TXAA, TSSAA is not tied to a particular manufacturer and operates in the entire spectrum of video cards that support improved graphics.

It is these qualities that make TSSAA best choice for the gaming industry. For version 9.9 temporal smoothing method (TSSAA) was created from scratch to modify the game engine BigWorld, which is used in World of Tanks.

algorithm TSSAA will be available in two versions:

TSSAA-LQ – «lightweight” version of the new smoothing method in image processing using a smaller number of previous frames;

TSSAA-HQ – highest quality antialiasing method.

At the moment, research is being conducted to improve the reconstruction accuracy and as a result, image sharpness in the distance.

Note: A new method of smoothing is only available for enhanced graphics. Enabling smoothing can affect the performance of the game. It is recommended to use the new smoothing algorithm on computers that meet the recommended system requirements and better.
If your computer has been the weak point of the processor, you do not notice the difference in performance between the maximum and the relief method, since the main burden falls on the video card.

New shade

For an update 9.9 have been completely reworked the shadows. As a result, improve their quality, as well as significantly reduce the load on the CPU and graphics card.

The new algorithm can not calculate shadows from static objects anew for each frame. As a nice bonus with this approach, we “free” (in terms of the load), we obtain the so-called “soft” shadows or Variable Penumbra Soft Shadow (realistic visual effect of increasing the shadow blur with increasing distance to the object – a source of shade).

The shadow of dynamic objects seriously alleviated and also became “soft” at maximum settings.

Improved contact shadows (Contact Shadows and Ambient Occlusion – a technology that creates a soft and realistic shading contact between objects), previously presented in the game algorithm HBAO (Horizon-based Ambient Occlusion). By algorithm 9.9 HBAO rewritten and optimized, thus improving the quality and temporal stability.

For medium settings instead HBAO written a simple but very fast and high-quality analogue SSAO (Screen Space Ambient Occlusion – diffuse shading in screen space), to optimize performance.

New lighting

Improved lighting model materials (BRDF). It is responsible for the way the light is reflected at different angles, or absorbed by the surface depending on its roughness (micro-relief).

The new model lighting (BRDF) is known worldwide as GGX, or Microfacet BRDF with a GGX distribution, – this model the most physically correct and located on the edge rendering technology in real time.

Changes lighting models allow more accurately track various types of materials, and will be most noticeable in the models of tanks, processed in HD-quality.

under a new lighting model BRDF was written algorithm RO (ReflectionOcclusion – tracing reflection) required to remove artifacts that arise when the reflected light passes through opaque objects. Roughly speaking, ReflectionOcclusion (tracing reflection) removes the reflection of light in places where they should not be.

Bloom has become much more stable at the maximum post-processing.

Optimization

In addition to the optimization of the calculation of shadows for improved graphics conducted a large number of system optimizations graphics engine, which reduces the CPU load when rendering static objects, trees and effects.

In version 9.9 the switching mechanism redesigned graphics settings presets more optimally configured for medium settings using a simple circuit in the drawing fog and bloom’a (scattering of bright light).
