An inbound update for rFactor 2 will bring the first 64-bit executables to the PC racing sim, developer ISI has confirmed.
Whilst ISI hasn't confirmed how many aspects of the currently 32-bit title will be upgraded in the update, it has been revealed the new rFactor 2 executables will allow players with sufficiently beefy PC systems to "take advantage [of the increased RAM efficiency] by running on larger tracks, with higher texture levels and more cars".
ISI has also revealed the move to 64-bit will allow a theoretical maximum RAM 'ceiling' of 17.2 billion GB to exploit. In contrast, rFactor 2 as a 32-bit title can only use up to 4GB of system memory.
That said, 32-bit rFactor 2 players will be able to experience memory use improvements once the inbound update is released, through ISI has gone on the record to say the 4GB limit " will always hang over you if you run high texture levels, or many opponent cars".
ISI has yet to state at time of writing when this update for rFactor 2 will be released.
