Major Game Running Speed Improvement

After months of intensive work by our programmers on optimizing game based on the feedback in this post: viewtopic.php?f=14&t=7197, we are pleased to announce that this version features Major Game Speed Improvements.
Our programmers have painstakingly reviewed and optimized key areas of the programming code and have even gone to great lengths to achieve the performance targets by rewriting the code when necessary. The result is a performance increase of over 50% on average, and possibly up to 100% faster in late games with numerous firms.
We believe that this version would resolve most of the game slowdown issues that have been reported.
New Interfaces
1) The toolbar at the left of the screen and the bottom menu bar have been completely redesigned, giving them a modern look.
2) Added [+][-] buttons at the left and right ends of each slider, for increasing and decreasing the value more precisely.
3) New graphical buttons for hiring and headhunting talents, replacing the original text buttons.
You can still use the same shortcut key ‘w’ to hire, and ‘u’ to headhunt.
New Feature for Banking and Finance DLC
Venture Capitalists
Venture Capitalists with billions of net worth will join the game when this feature is enabled.
Venture Capitalists only invest in companies in pre-IPO rounds. They are committed to long-term investments and do not actively trade stocks.
For details, please see: https://www.capitalismlab.com/banking-d ... pitalists/
New Scenarios for Digital Age DLC
3 New scenarios for Digital Age DLC. (2 more are planned in the next major version 6.7.00.)
Modding Improvement
The upper limit of product types has been increased from 820 to 900.
Layout Plan Library
New feature: Separate Layout Plan Libraries for MODs
Since a Mod may have a vastly different set of products than the standard game, the game now uses a file structure that maintains a separate Layout Plan Library for each Mod that you have played. The way layout plans are now organized allows for much easier search and management of layout plans when playing Mod-enabled games.

Audio Improvements
1) Improved sound effects for the event trackers.
2) Additional music tracks and improved music playback quality.
3) The ability to play custom music files. For details, please read readme.txt in “Music” subfolder under the game folder or read this post: viewtopic.php?f=7&t=7768
Manager’s Guide Improvement
The Manager’s Guide now has two categories of content: 1) the information about business functional units in the 3x3 layout as in the previous version and 2) a new category called “Tips”. Currently it only has a couple topics. We will be adding more topics to it in future updates.
AI Improvements
After an AI corporation has been in operation for a few years, the AI will stop using pre-defined layout plans with multiple products in factories and solely use wild-card layout plans with settings of only one product per factory.
The idea was discussed in this post: viewtopic.php?f=14&t=7483
2 New Challenge Games
1) Real Estate Mogul
2) Software Giant (requiring Digital Age DLC)
Improved the Cities report under the City Economic Simulation DLC
The GDP page of the Cities Report has been improved with better graphics and new help buttons for explaining the effects of the GDP.

1st GDP component: Consumption is the total value of goods and services that are bought by the population simulated in the game.
2nd GDP component: Investment is the total investment made by the player and AI corporations in setting up new businesses.
3rd GDP component: Government Expenditure is the total expenditure of the city government, which can be run by a player controlled mayor.
4th GDP component: Net Exports equal to exports minus imports. Imports occur when companies in the game purchase products from suppliers in a different city. Exports occur when companies sell products to business clients in another city.
Together, they contribute to the GDP growth and make a huge impact on the economy, leading to booms and busts in the economic cycle, affecting inflation, employment rates, wage rates, and interest rates.

For example, when your company embarks on a large-scale business expansion in a city, it increases the Investment component of GDP, which in turn contributes to the GDP growth and kicks the economy into the high gear. The newly established companies create jobs for the city, lowering the unemployment rate. Subsequently the tightening labor market will force companies to raise salaries of their employees.
Further along in this chain of effects, a higher wage rate leads to increased consumer spending, setting the stage for inflation to rise. When rising inflation is unchecked and eventually runs rampant, the central bank will have no choice but to put a break on it by hiking the interest rate aggressively, which will inevitably drag the economy into recession.
New Script Variables
1) A new script variable for setting your corporation's brand strategy.
Brand Strategy=<Corporate Brand/Range Brand/Unique Brand>
Use this line to set the player corporation’s brand strategy to a specified strategy in the beginning of the game.
2) A new script variable for Telecom
[Digital Age DLC]
Telecom Customer Stickiness = <1 to 1000>
(default value: 100)
If you think your telecom gains customers from rival telecoms too slowly, you may use this variable to change the speed at which it gains or loses customers in relation to rival telecoms.
A value lower than 100 means that customer stickiness in telecom will be lower than the default setting and the gain or loss of customers will happen faster. A value higher than 100 has the opposite effect.
The formula is:
<the original rate of gaining/losing customers> X 100 / <this Telecom Customer Stickiness variable>
For example, if Telecom Customer Stickiness is set to 20, then
The new rate of gaining/losing customers will be 100 / 20 = 5 times of the original rate.
