This is far from intuitive, but since you are stressing your GPU more at higher quality settings, the algorithm will have to drop the resolution to manage and hit those 10 ms. Unfortunately, the game mostly played around level 3 with the out of the box settings.Īlyx does not give you a direct way (besides using the console) of controlling the fidelity level from the graphics options, but you can control it in an indirect way: using higher graphic presets, can result in a lower fidelity level. Level 3 on the other hand, was quite more blurry. The geometry of the buildings far away was solid without shimmering. I could easily make out the individual leaves of the trees at the street level and the railings of the balcony at the first floor were rendered beautifully. Level 8 resulted in super clear and detailed textures. This is because Alyx is handing a larger buffer to Steam VR’s compositor as fidelity level increases. Notice that the higher the fidelity level, the larger the screenshot size. To see the difference better, you can view the in-game screenshots on a computer monitor: 0, 3, 6, 8. Notice how the GPU time graph increases with the level.ĭue to gif compression, the difference may not be that apparent. So, the game’s resolution can be different than the headset’s. It’s handed over to Steam VR’s compositor, which applies lens correction and renders it to the headset’s native resolution. When a game renders a frame, it isn’t sent straight to the headset. Steam VR render scaleīefore diving into Alyx’s dynamic resolution implementation, we need to first look at how Steam VR handles resolution. If you’re interested just in the tips, you can skip to the TLDR paragraph. I will also get into some details in the end of the article about the issues I faced when running VR from a laptop. I run Alyx on my PC, having a GTX1080, and on my Razer Blade Advanced 2019 model, having an RTX2080 Max-Q. So, here are my findings which will can hopefully help you get a higher resolution picture from the game. If you’re like me, you’ll understand why I spent my first 2 weeks with the headset playing with the settings instead of enjoying the actual game. It comes as no surprise that it has various graphic options to tweak, on top of those provided by Steam VR such as “render resolution” and “motion smoothing”. Alyx and the Index live in the PC space and playing with it reminded me of the difference between console and PC gaming in terms of tweaking and out of the box experience.Īlyx was built to work with a variety of VR headsets and different setups in terms of computing power. I have been a happy PSVR user for more than 1 year and due to Alyx, I got the Valve Index. Half-Life: Alyx performance analysis (or: why low graphic settings produce a sharper image)
