A new tool has come across on the Avsim forums. Just like the realism shader pack, but with more options.

Full post below as well as the links:

“Hi guys!
I’m really impressed with Pe11e’s Realism Shader Pack ability to enhance P3D visuals without manual fiddling with shaders.
RSP v.1.1 contains some HDR, clouds and lighting tweaks that could be fine tuned.
To provide the ability to manage all parameters of discovered tweaks, I’ve decided make a special tool: Prerar3D Tweak Assistant (PTA).
Not only known tweaks are fully customised by PTA, some new tweaks and capabilities were included in that tool to get max. flexible management.
If you liked visual improvements that can be achieved by shaders modifying, perhaps you should try this free tool.
Two separate versions for Prepar3D 3.1 and 3.2 are available from site:
There’s also the description of capabilities, installation and use PTA there.
Some screenshots here: http://1coder.ru/PTA/screens.html
Please feel free to post any issues here!

The main features

– 20+ different tweaks with fully customisable options.
– New custom shaders, adapted from SweetFX. It can be used natively in Prepar3D without Reshade!
– All tweaks with config parameters and custom shaders grouped into presets and can be stored in separate files with comments and shared with other people.
– Strict control of sim shaders integrity and the easy recovery mechanism for original shaders and config files.
– Detailed help on each tweak and its options.
– Logging of all operations with detailed errors messages and hints.
– Customisable skin of tool interface.

In this version you get fully parameterized:
Clouds tweaks: scale the width and height of clouds puffs, clouds shadows extended size, disable volumizing calculations for clouds, reduce cloud brightness at dawn and dusk, reduce “popcorn” at far distance.
Shadow tweaks: boost light on the illuminated areas, make shadows deeper, autogen shadows intensity.
Terrain tweaks: atmosphere scattering effect, include new (not published yet) alternate variant for IFR flights; boost urban areas luminosity at night.
NEW water tweaks not published yet: tune waves speed, tuning water refraction and reflection coefficients and surface granularity, that will result in really new water appearance. Also you can get FSX-like reflection of the sun.
HDR shader tweaks: new ability to adjust whole scene tone, alternate tonemap operator, customizable contrast tunung. Also you can turn off HDR luminance adaptation effect (new tweak);
NEW experimental FXAA antialiasing tweak: provides full control of FXAA shader specific parameters. – NEW custom shaders Sepia and LumaSharpen adapted for Prerar3D renderind engine.”
