Gran Turismo 7’s latest money-earning bug, which takes advantage of the credit rewards adjustment that was recently implemented in the Spec II update, has now been added to Polyphony Digital’s “Known Issues” list in anticipation of a future patch.
Technically speaking, the issue has been there for a very long time, but it wasn’t until Custom Races introduced bigger payouts that it became a real money maker and the fastest way to gain repeating credits in the game.
PD has added a specific bug to the “Known Issues” page that essentially exploits a weakness in the way Custom Races determine the difficulty of a race and, consequently, the credit awards for winning the event.
Simply put, the base Performance Points (PP) of the cars chosen for the race—along with any changes made to those cars—are used by the game to calculate the difficulty of the race.
This implies that even though the game still views them as top-tier vehicles, players can choose incredibly powerful cars and badly cripple them with a mix of bad tires and excessively short gearing, making them easy to beat in much lower PP vehicles.
The player automobile can also be among the slowest in the game, but it can be made into a high-speed weapon by using different tuning techniques, such as engine swaps, all the while maintaining the appearance of an antiquated, low-powered vehicle.
The best ways to accomplish this are covered in a number of ways that are circulating around the internet, including this very GTPlanet topic. Still, almost any method can provide more than four million credits in an hour.
The recommended setup has the player operating a K20 turbo-swapped Abarth 595 in a convoy of Dodge Tomahawk X cars with more than 2500 horsepower, all on Comfort Hard tires and geared to travel at speeds under 150 mph. However, a lot more work needs to be done to get the car to drive properly and not try to flip itself over or crash.
When applied at Daytona Tri-Oval, this strategy also creates the potential for a “AFK” earner, or someone who is “away from the keyboard.” To scrape around the outside wall, use elastic bands to hold different controller buttons in place (with motion steering, to avoid stressing the thumb sticks). If the player doesn’t strike the AI cars, they will receive a Clean Race Bonus.
This method won’t last long, though, as PD plans to close the vulnerability in a later release. A note regarding the inaccurate computation is now present on the game’s Known Issues page; however, this should be fixed by the time of the upcoming content release.
That shouldn’t be shocking considering that Kazunori Yamauchi earlier expressed his desire to see Gran Turismo 7 avoid “a situation where a player must mechanically keep replaying certain events.”
