Even if your PC is getting honest-to-god , it does n’t have to mean that play the latest secret plan is out of the query . While some carrying into action - boosting feature were previously reserve for those who own one of thebest GPUsor one of thetop processors , modders have now step in to change that narrative .
As a outcome , a mod enables usingNvidia ’s DLSS 3(or rather , AMD ’s FSR 3)on much old graphics cards . Confusing ? Do n’t worry , it makes a lot more sense than it seems , and you could apply it to boost your PC ’s gaming performance by up to 75 % .

DLSS is Nvidia ’s game - exchange frame propagation engineering science . At least on paper , it ’s shut away to RTX 40 - series graphics cards . AMD ’s FSR 3 is the twin to Nvidia ’s DLSS 3 , and it ’s open - seed , meaning it ’s available on many more computer graphic cards than Nvidia ’s exclusive tech . On the surface , you ’d think that this would mean that frame generation should be available to a wide ambit of gamers , but it is n’t . This is because the adoption of FSR 3 has been very dim , and as of today , it ’s only available in four games .
However , Digital Foundry late spotted a mod that work with all the games that support DLSS 3 natively . The mod fundamentally tricks the computing machine into believe that the microcomputer is track down an RTX 40 - serial publication card , but it is , in fact , usable on old RTX GPUs ( 20 - serial and 30 - serial ) . The trick is that it does n’t run DLSS 3 ; instead , it enables the open - source FSR 3 that works on many graphics card .
basically , it lets you bleed games with FSR 3 that would not otherwise be able to run it , not due to GPU limit , but due to the fact that the feature is unavailable in that picky title . The funny part ? It does n’t work on AMD GPUs .
fly the coop the mod need shoot DLL file into a biz ’s directory , editing the register , and finally , enabling the feature in the game . All of that makes this FSR 3 disguised as DLSS 3 body of work , and accord to Digital Foundry , it seems pretty brilliant .
Testing the mod with several AAA games , such asCyberpunk 2077 , showed a great functioning boost on an RTX 3080 . With the mod running play , the RTX 3080 was able-bodied to keep over 100 frames per second ( fps ) at 1440p on RT overdrive mode ; without it , it hit a much less impressive 60 to 70 Federal Protective Service . This marks an up to 67 % boost at 1440p . Spider - Man : Miles Moralessaw even greater gain , with an uplift of up to 75 % .
Unfortunately , running this DLSS 3 - slash - FSR 3 amalgamation results in some downsides , including visual artifacts and higher latency . These issuing have mostly been iron out out in games that support FSR 3 , but seeing as this is just a mod , it ’s no wonderment that it ’s not perfect . turn back outDigital Foundry ’s videoif you ’d like to learn more about the mod and potentially essay it out for yourself .
Turning your older Nvidia GPU into a watercraft for AMD ’s FSR is n’t the only affair you may do to gain some extra frame pace . PCGamerrecently dug up an interesting GitHub project referred to asReBarUEFI , which is a BIOS mod that will allow you to runResizable BAR ( ReBAR)on sr. PC dating as far back as 2011 that would n’t otherwise support it . ReBAR is a feature that lets your central processing unit get at the full frame buffer of the GPU instead of being set to only 256 MB , which is the case on hardware that does n’t substantiate it .
old motherboards often do n’t support Resizable BAR , but the mod allows you to get past these restrictions and run it . ReBarUEFI tot up the place setting in the BIOS on older motherboards , allowing the processor and the GPU to communicate in effect . This translate to a carrying into action rise of up to 12 % , according to the mod ’s author , and maybe much more on an Intel Arc GPU , as those reasonably much require ReBAR .
While the DLSS 3 mod seems easy enough to enable , ReBarUEFI is a small trickier . If you really want to give it a go , we recommend scan through the instructions carefully and go in with the idea that something might go wrongly — and if matter go wrongly in the BIOS , your entire microcomputer may be affected .
Either style , it ’s great to see hoi polloi detect ways to bring New technology to old microcomputer , even if it takes some tinkering to get them to make .
