Now there are cacti, small rocks, grass and buildings which are in the desert in the default version, like water towers, watchtowers and rusty ships too.
You can disable them independently to test how much they affect performance.
And you have now a "compass" in the ashtray, which points at the starting house, and a bit more gas, if you want to go on a longer adventure in the big desert :D
There is a binocular too, but I forgot to adjust it's camera, so it may behave buggy sometimes.
Please test it if you want, so we can see if the performance is still better, than in the default version :D
This is just a test version again, so there is no road, no loot, you can't save, there is no main menu.
Next thing will be the road, then maybe proper buildings and fixing the loot spawn and save system.
Thank you for your patience! :D
Edit:
You can access the test version by right clicking the game in you steam library, click properties, then betas tab, and there from the drop down menu select "beta - upcoming version test" and it will download.
