Your DeusEx problem might be related to a general Steam issue, which affects random games on random machines. Most likely a conflict between Steams copy protection and the way vorpX attaches itself to games. The next update, which is due sometime this week, has some changes in this regard, so there is a chance that your DXHR issue will be resolved, provided it is related.
Not sure what the issue with Black Mesa might be, since I don’t think it uses any copy protection. Can’t replicate the issue here, unfortunately.
no update i’ve heard of. I was only able to get bf3 running at work by going to ALT_tab etc.. and it worked twice. Since then no games worked on my machine. Do you close or extend your display configs of your rift..For unity engin some games will only work in extended displays. i wonder if it’s the same problem you got
