[The Exiled]

Za uključiti ReBAR krajnji korisnik općenito mora imati nešto od novijeg hardvera i obavezan je BIOS upgrade uz uključivanje UEFI (Secure Boot) + GPT "sitnica".

Obzirom da Intel s ovim ARC modelima cilja na budžet gaming, većina tih sustava ili uopće nativno ne podržava ReBAR ili ljudi ne žele uključiti hrpu popratnih pizdarija, jer ARC GPU bez ReBAR opcije gubi 40% performansi.

• Intel is working on driver optimizations for systems that lack ReBAR support, but general advice from Petersen for old platform users, is to stick with other vendors.
  
  
• As a result, Arc GPUs loose almost 40% performance when used without ReBAR and this is unlikely to change for 1st Gen Arc GPUs (Alchemist), but Intel is working to reduce this issue with future architectures.
  
  
• "We thought that we would be able to leverage the integrated graphics software stack, and it was wholly inadequate for the performance levels, gaming compatibility, etc. that we needed.
