Now it’s almost standard and if you have an Intel Arc graphics card, you absolutely need it switched on. But if your gaming PC is a wee bit on the old side (e.g. you’re using a 4th Gen Intel Core processor), then you’ve probably been out of luck as the motherboard will almost certainlynothave the feature anywhere in its BIOS.
That’s where the ReBarUEFI comes in, as it will just add the setting to one of the menus. Looking at the list of instructions, though, may well make you wonder if it’s really worth going through all those steps for a small performance boost. Well, the mod author claims that they get up to 12% more performance on a Core i5 3470 system with a Radeon RX 580 graphics card.

Unfortunately, I don’t have an old PC to hand to be able to test the claims but even if you didn’t get as much as 12% on your own system, any extra performance that doesn’t involve buying new parts or overclocking is certainly worth investigating.
That said, it is also worth noting that while AMD and Intel liberally enable Resizable BAR in their drivers for countless games, Nvidia is far more selective, and only a relatively small number of games are given a large BAR value. You can override this with tools likeNvidia Profile Inspectorbut I’ve never found it to make much difference.
The biggest gaming news, reviews and hardware deals
If the ReBarUEFI project sounds like something you want to test out, just remember that there’s quite a difference between modding a BIOS and tweaking a driver setting. Years ago, I would have jumped on this in a flash, but these days I’m very much in the ‘if it works, then don’t change it’ camp.
The process looks quite complex, with various extra steps required for different configurations, so don’t blame us if you somehow end up borking your motherboard!
