Quake II RTX Performance Review

RTX 2080 Ti Default Quake II RTX Performance

On this page we are going to start quite simply at looking at performance in Quake II RTX using the default game settings on an ASUS ROG STRIX RTX 2080 Ti OC video card.  We are simply starting the game up and utilizing the default RTX settings which uses a “Medium” Global Illumination setting.  We are testing at 4K, 1440p and 1080p resolutions in our three timedemos “demo1.dm2” and “crusher.dm2” and “massive1.dm2” as detailed on the previous page. 

In this first graph we are showing our timedemo run of the built-in demo1.dm2 timedemo.  This with the default Quake II RTX settings using “Medium” Global Illumination.  Starting off it is obvious from the get-go 4K is out of the question in terms of performance, averaging not even 30FPS.  Only at 1440p do we start to see what seems like playable performance in this demo at 63FPS.  Finally, 1080p is most definitely fast enough giving us 104FPS. It seems resolution plays a major part in performance with these features enabled.  There is a large 40% drop going up to 1440p from 1080p and a bigger 56% drop going to 4K over 1440p.

In this second graph we are showing the same exact game settings using the default settings of “Medium” Global Illumination.  This graph shows us the performance in the “crusher” demo.  This custom-made demo run is much more intense on performance.  It brings the average FPS at 1440p below 60FPS now to 55FPS.  4K is still unplayable and 1080p is 88FPS.  There is a 37% drop in performance going from 1080p to 1440p and a 56% drop going to 4K from 1440p.

Finally, in this third graph we are showing the “massive1” demo at the same default Quake II RTX settings of “Medium” Global Illumination.  4K performance is still very unplayable while 1440p is close to 60FPS and 1080p is very playable at 93FPS.  There is a 38% performance drop going up to 1440p from 1080p and a 56% drop going to 4K.


What we learn from these results is that resolution has a large affect on performance and what is playable.  There is a larger drop in performance between 1440p and moving up to 4K than there is from 1080p and moving up to 1440p.  There seems to be close to a 40% drop in performance between 1080p and 1440p but a larger 60% drop moving up to 4K.

In terms of what is playable, we did play the game and found that with default settings 1440p is playable on “Medium” Global Illumination with this video card.  Therefore, keeping the default settings does allow 1440p to be playable for that higher resolution experience.  However, moving up to “High” Global Illumination does mean having to drop to 1080p to be playable.  We tried to make 4K playable, but even with Global Illumination OFF it was still not playable.
