Personally, I'd stick to 'two' to retain the most impact without unduly stressing the GPU.īeyond glass, water rendering also gets a big upgrade - it has density now, meaning that it has the ability to absorb light. It's not infinite though as this would scale infinitely in terms of GPU load, but there are up to eight levels of reflection and refraction you can choose from. In such surfaces, you can see your reflection and the reflection of your reflection and so on and so forth - the so-called 'hall of mirrors' effect. With this you can see how the glass itself is not just an infinitely thin reflecting plane, but rather something with its own volume where light has to enter it and then leave it.Īdditionally there are some extremely rare perfect mirrors now added into the game that support multiple recursive reflections. On top of those improvements, there is also the option to enable glass thickness that adds in a layer of refraction and reflection for the opposite side of the glass. Glass reflections are of a higher resolution, and the reflections themselves are more clean and stable. Everything you need to know about the new Quake 2 RTX upgrades.Īnother big change occurs with how glass rendering is achieved and it's now more accurate in several respects. Naturally, these screens cast out their own light onto surrounding materials capable of reflecting them. Alongside metals, glazed materials including various computer monitors in-game now support picture-in-picture security camera feed footage, replacing static textures from the original release. The reworked textures also add more material diversity and variety to scenes, which in the launch version had many textures looking extremely similar in how light affects them. Version 1.2 now sees individual cartridges exhibit metallic sheen and emphasise the coloured metals on the jacket. For example, the original remaster's shotgun shells in ammo boxes use matte materials that show little differentiation between the box material and the shells themselves. It's all change in 1.2, with art changes that dramatically change and improve many scenes.

The original release had metalwork that appeared to lack much in the way of specular properties, so even with the hyper-realistic path traced lighting, the material looked more like stone than metal. Metal and how it interacts with lighting has changed immensely. A key focus for the 1.2 upgrade has been to re-assess many material properties and get them looking just right. While the original Quake 2 RTX launch used physically-based variants of Quake 2 XP textures, not all of them appeared to receive the same level of love and attention. One might think that Nvidia would simply move on from the Quake 2 project and concentrate efforts on the ray traced upgrades for other titles that are being worked on behind the scenes, but the improvements to the 1.2 upgrade are quite profound - and the most noticeable change comes from upgraded art assets.

It's one of the most impressive examples of hardware-accelerated RT and thanks to the new 1.2 patch released a few days ago, a phenomenal game now looks a whole lot better.

So it is advised to either disable the flare gun on MP servers, or to make the servers only available to Q2RTX players.Quake 2 is over two decades old and yet the id Software classic is one of my favourite games of this year, radically re-invented from a visual perspective thanks to the ray traced remastering from Nvidia's Lightspeed Studios (based on original work by Christophe Schied).

If both Q2RTX and other clients participate in a multiplayer game, and the Q2RTX user fires a flare gun, other clients that see the flare will disconnect because they do not understand what that means. Quake II RTX uses the regular Quake II network protocol (version 36 from Q2PRO), but the flare gun is an extension to the protocol. The sv_flaregun and sv_restrict_rtx settings have been added mostly for compatibility reasons. If multiple dedicated cooperative servers are started from the same installation directory, they should use different directories to save game state. Sv_savedir: path to the directory within baseq2 where the server will save game state in cooperative play mode. Sv_restrict_rtx: if set to 1, makes the server available only to clients playing Quake II RTX other clients like the regular Quake II or Q2PRO will be rejected. 0 means no flare gun, 1 means spawn with the flare gun but no ammo, 2 means spawn with the flare gun and 5 grenades (because the flare gun uses grenades).

Sv_flaregun: controls whether players spawn with the flare gun and ammo for it. We have added some more variables to control RTX specific features:

Many of the console variables useful for dedicated server administration are documented in the Q2PRO server manual - since Quake II RTX is derived from Q2PRO, these variables still apply.
