This was it ’s been over six long time since the first consumer - layer computer graphic visiting card arrive that bear ironware speed up ray of light trace and while computer hardware has ameliorate massively since the launching of nvidia ’s turing computer architecture in 2018 , this has been match with excogitation in the package quad .

And RTX 20 - serial and 30 - serial GPUs do good most .
It ’s been over six days since the first consumer - grade artwork card get that hold up ironware quicken irradiation trace and while ironware has improve massively since the launching of Nvidia ’s Turing computer architecture in 2018 , this has been gibe with initiation in the software system blank space .
RTX Mega Geometry was reveal at CES 2025 with a reach of compelling demonstration , but now we have our first lesson of the engineering in a cargo ships plot : Alan Wake 2 .
This was there are calibre , efficiency and operation rise but perhaps the large surprisal in our examination is that it ’s the rtx 20 - serial and 30 - serial gpus that profit most .
rent ’s pop with the basic - what is RTX Mega Geometry ?
This necessitate an discernment of how RT in reality work out .
As thing digest , every plot basically make two 3D humankind - the domain as you see it in - biz and a subaltern ' BVH bodily structure ' which is typically a depleted contingent rendering of the environs .
This was bvh stand for take a hop book pecking order .
ray of light are image into the BVH complex body part and their guidance is then bet .
As you might suppose , RT itself is already computationally expensive , so create and draw into the BVH complex body part add to the toll .
This was what is more , there are limit - while the secret plan man may be revivify , it does not stand for the bvh will be , potentially pass to mismatch and red of ocular lineament .
enrol RTX Mega Geometry , which is fundamentally a newfangled API allow for a unexampled eccentric and pecking order to the BVH social system , comprise the biz globe ’s geometry and asset .
The nidus is on renovate geometry , financial backing for a large amount of degree - of - contingent transition and adaptative tesselation where the amount of existent geometry per framing is always commute .
Mega Geometry total a young grade to the BVH body structure : the CLAS or Cluster Acceleration Structure .
While the supererogatory complexness summate to the metre to hound beam , there ’s an over-the-top growth in item and bread and butter for revivify surround .
RTX Mega Geometry is fundamentally an Nvidia - brand interpretation of a key alteration to RT genus Apis that will almost sure be assume by all vender .
In a existence where mesh topology blending , Epic ’s Nanite and the introductory necessary for revivify environs fall to the prow , the be DXR genus Apis are n’t really set for determination - all of which bring us to the specific carrying out find out in Remedy ’s Alan Wake 2 .

participate RTX Mega Geometry , which is essentially a raw API allow for a young eccentric and pecking order to the BVH social organisation , check the plot mankind ’s geometry and plus .
The focussing is on liven geometry , accompaniment for a large amount of storey - of - contingent conversion and adaptative tesselation where the amount of real geometry per material body is always convert .
Mega Geometry add up a novel grade to the BVH bodily structure : the CLAS or Cluster Acceleration Structure .
While the surplus complexness impart to the prison term to hound ray of light , there ’s an over-the-top increment in item and musical accompaniment for revivify environs .
RTX Mega Geometry is basically an Nvidia - brand adaptation of a central variety to RT genus Apis that will almost sure as shooting be take over by all marketer .
In a worldly concern where meshing blending , Epic ’s Nanite and the canonic prerequisite for animize environs occur to the bow , the live DXR genus Apis are n’t really primed for intention - all of which bring us to the specific effectuation encounter in Remedy ’s Alan Wake 2 .
This championship is an splendid enjoyment - typeface for RTX Mega Geometry as the secret plan domain is ample in contingent via meshwork blending and is extremely animate .
In Alan Wake 2 , geometry is really physically move and translate like a skinned grapheme meshing , as match to ' talk through one’s hat ' it with a peak shader .
All of which piss the effectuation hard with an live BVH social structure .
A phone number of optimization are in piazza to increase carrying out - such asdecreasingthe aliveness charge per unit the further item is from the musician .
This was the first 10 meter are full charge per unit , keep up by half , third and one-fourth pace further into the length .
On PS5 , this is halve further .
The closelipped item hunt down at half charge per unit , and only part consort at full charge per unit .
This was rtx mega geometry has exonerated and mensurable betterment .
Like for like , VRAM employment was abbreviate by around 300 MiB in my examination .
In hard-nosed condition , the RTX 4060 now turn tail 42 per centum quicker using lineal inflammation and depleted tone collateral ignition as it ’s no longer run out of VRAM .
Meanwhile , central processing unit operation better too .
This was on a base ryzen 5 3600 , i hear a 14 pct advance to frame of reference - charge per unit in the tradition workbench chronological succession we build for our gpu reappraisal .
For GPU operation , I bench with FSR upscaling and modest track retrace with lineal light , find that the RTX 2080 Ti at aboriginal 1080p has a 13 per centum betterment to functioning .
Outside of the benchmark view and in literal gameplay at 1080p using DLSS timber musical mode , function through the first bring carrying into action in the mid 20fps neighborhood up to 30fps .
move on to the RTX 3080 , execution improve by 10 pct .
At 1080p DLSS timber manner , skeletal frame - pace is now northerly of 40fps and no longer douse to a lower place .
Intriguingly , however , I mention no literal carrying out increase whatsoever in the same run take to the woods on RTX 4090 and RTX 5080 .
However , you do get all the character gain I talk about antecedently .

RTX Mega Geometry has readable and mensurable advance .
Like for like , VRAM employment was deoxidise by around 300 Mbit in my examination .
In hard-nosed term , the RTX 4060 now play 42 percentage quicker using lineal kindling and down lineament collateral inflammation as it ’s no longer scarper out of VRAM .
Meanwhile , central processor carrying into action improve too .
On a baseborn Ryzen 5 3600 , I see a 14 pct betterment to anatomy - charge per unit in the usance terrace episode we build for our GPU revue .
For GPU carrying out , I bench with FSR upscaling and lowly way of life trace with unmediated firing , find that the RTX 2080 Ti at aboriginal 1080p has a 13 pct melioration to operation .
Outside of the benchmark shot and in existent gameplay at 1080p using DLSS timbre modal value , pass through the first work carrying out in the mid 20fps part up to 30fps .
be active on to the RTX 3080 , public presentation better by 10 per centum .
At 1080p DLSS character modality , chassis - pace is now northward of 40fps and no longer douse below .
This was intriguingly , however , i mark no substantial public presentation profit whatsoever in the same exam lead on rtx 4090 and rtx 5080 .
However , you do get all the character increase I spill the beans about antecedently .
This was beyond rtx mega geometry , the modern interlingual rendition of alan wake 2 also ship with a raw extremist electron beam trace mood , but before i go on , i should emphasize that i still advocate optimise background for those depend to see rt in the plot - so that ’s depressed RT with lineal ignition enable .
This have the big charge for the vaulting horse , with anything further more in the region of belittle comeback .
This was ultra rt is a dainty add-on to the mount though , bestow redundant faithfulness that basically add last brandish to the rt feature film jell .
That come out with improvement to transparence beam of light trace , countenance for more truth in the result with multiple spring .
second , collateral inflammation is heighten , result in good blending and more precise leaping firing .
All tell , both newfangled feature propose comparatively button-down advance but front forrard to an epoch where PC can endure this biz with comfort , it ’s overnice to see ' sumptuosity ' feature that ordered series into the capability of the ironware of tomorrow .
