Enabling RTX on 1080 TI

[Blackwolf]

Now before everyone gets their tits in a twist on this topic I would like to keep a few things in mind:

1. We are still being affected by a GPU shortage, and I'm not paying scalper prices.
2. Some games that I own, such as Control and Ghost Runner, are (in my opinion) optimized fairly well, and run perfectly fine with ray tracing enabled at 720p @ 30FPS, which doesn't bother me much since [A.] I'm using a 1080p display and I sit a decent amount away from it, and [B.] they're single player games anyway.

Now, with that out of the way, I would like to know if there is a command line option to brute force ray tracing on in Doom Eternal, since the option is greyed out because I'm using a 1080TI instead of a 20 or 30 series card.

not that i know of

how can a non-rtx card run ray tracin'? or am i just dumb?

it can but it results in a significant performance reduction.

for example if i turn on all rt effects in control on my 1070, it runs at around 5-10 fps.

All cards can run raytracing in theory. The RTX cards just have an extra chipset exclusively for that job in addition to the base power, which, in case of the 3000 series ist pretty high in itself. And they can use DLSS.

Bad explanation. I don't know the technical terms for all that ♥♥♥♥, but I think the concept is like this.

Any card can technically run ray tracing as it's just mathematical formulas. The problem with older cards is that the CUDA cores can't solve the equations fast enough to give decent performance. The performance is bad because the cores are busy solving these equations and trying to render everything else, that's why 20 series and up cards have cores that are only used for that purpose

Possibly.

Check the Digital Foundry analyses of it. At the end of the video Alex goes into console commands and Cheat Engine that enables you to unlock additional raytracing options not available in the in game settings... perhaps there is also a way to force it on no matter the GPU:

Worth a look.

Exactly. Without dedicated RT hardware, the process will be much slower and possibly unplayable and that's why it's greyed out.. but yes, any card can render ray tracing for better or for worse.

♥♥♥♥♥♥♥♥♥♥♥♥ why would you play at 720p 30fps when you can play at 1440p 60 fps. i cant with these steam posts i swear its the most braindead ppl on here

stop trolling the steam forums its getting annoying i spend all day browsing here since my 970 cant run any games i like and trolls like you make my day worse

pretty sure you can run this game just fine on a 970.

Agreed, my previous system had a 970 card and ran the game just fine on High.

I played MetroExodus RTX Enabled with Max Details using my GTX1070, it plays like a HighQuality PS3 trailer title (due to low Resolution needed but sustains 30-40fps with RTXGI in Metro) Played Control, Battlefield 5 & Metro on my GTX1070 in RTX modes.

It shouldn't be. For me it isn't, and I'm using a 1660 Super.

Will RTX run? Sure. Run very well? Absolutely not.

I'm still running with a GTX 970 and Doom Eternal performs just fine on medium to high settings.
