Did this just start? Put your specs in your next post also please. you have not updated is this intentional?

Removing the Update by way of Windows Restore is the out. you could also take a look at the change log for 8.1 to correct (if possible) the internal change that is causing the slowdown.

U can always do a system restore. and U can also tell windows not to update to that ver. of win8.

Logical. They did muck with the DX9 files for the new driver releases with both of those ver. you mention.

Once you get through this error, try to keep 2 copies of the sim. on your PC. Don't be quick to update until U see how others are getting on with the newer ver. I know this was an update by way of Steam. but the rule applies just the same. Opt. in to the Beta on steam if U prefer to use it. and download the 1.2.8 Beta of DCS. until fix is offered if U wish that is.

heat and memory are the only thing that come to mind with this issue. you could try raising and lowering the graphics settings to narrow it down a bit. system ram ver. video ram kind of test.

Have you used Steams verify file yet? u can find it in the help section of their interface. I would also download the latest ver. from DCS 1.2.8 and use it instead of the steam ver.

It was discussed as a secondary topic in the missile avoidance thread. It does deserve its own thread as u have started, it was concluded there also that the manpad wasn't realistic.

Have U tried going back to older ver. of graphics driver?

Sure do. It's in the bug report section. This one should be under object count slowing sim to a crawl kinda post. It is there.

Although there are other potential causes this sounds like Memory error to me. Have U mucked with windows caching? (Virtual Memory)

No key Bind errors? Have U deleted the DCS file in our user account so that it can be rebuilt after DCS starts back up again?

I have seen several users of Win8 with no errors. U do not click cancel on the DX9 set up do U? Having trouble imagining the error here.

I am experiencing the same as u. Some hidden common denominator for sure.

Check file sizes to make sure both have same size for install. could be glitch in the matrix. (Missing File when downloaded)?

Bing, Google? Choose as u wish.

That is true. I remember other users having that issue. Replacing the file was their method of fixing it.

The issue u describe sounds like a motherboard issue. More specific a controller on the MB. (slow death maybe?) or only in DCS?

DocFu is this the Beta? I see u are in DCS World non Beta area just want to be sure. Also I keep 2 ver. of the software on me PC just in case of buggeee updates like this. 1.2.7 on SSD and Beta on the HDD. Helps keep u ingame till bugs are worked out.

Sense others are using the software with no errors, even in Multi-Plater Lan Parties He might have a point here.

You are running the Steam ver. of DCS World, I am not sure if they added it in their ver. (Anyone?) You should download and run the DCS ver. of their software. It is running butter smooth on my system. DCS World Download Page http://www.digitalcombatsimulator.com/en/downloads/world/dcs_world/

Flew for about 4 1\2 hrs. yesterday had no issues. Single Player No mods. Ran Butter Smooth on my system.

Heat issue maybe?

Did you try the repair function in the software yet?

I tend to agree. sounds like overheating issue.
