OnAlienware Posted March 21, 2014 Share Posted March 21, 2014 (edited) I have drastic drops in performance (from 60fps to 20) occurring during certain transitions in-game. On the tank range, I'll get 60fps in the daysight and gunner's station, but if I go to thermal, then return to either, it'll regularly drop to 20.I've had the same performance drop transitioning to the "Events" view in the AAR.Interestingly, using the Windows key to pop in and out of the sim often (temporarily) fixes the issue. The thermal view, regardless, seems to always maintain its FPS.I'm using Windows 8.1 on an up-to-date Asus G750 (i7, GTX780M etc.) and McAfee antivirus.Please help! Love the sim.

Members Ssnake Posted March 23, 2014 Members Share Posted March 23, 2014 Is the low frame rate happening in EVERY vehicle's thermal sight, or just in one or two (e.g. the Lemur RWS, but, say, the Leo 2A4)? 0 Quote Link to comment Share on other sites More sharing options...
OnAlienware Posted March 25, 2014 Author Share Posted March 25, 2014 Ssnake, thank you for the reply.I wasn't clear. The thermal view is the only view which maintains my FPS. It's the other views which experience the drop.I'll go from 60fps in any view, go to thermal and enjoy 60fps, and then have my fps drop to 20 when leaving thermal.This drop can be triggered by other transitions, too (going to the "Events" view in the AAR, for instance).Thanks! 0 Quote Link to comment Share on other sites More sharing options...

Jam Posted March 25, 2014 Share Posted March 25, 2014 I experienced this a while ago with a certain Nvidia driver. What driver version do you have installed? 0 Quote Link to comment Share on other sites More sharing options...
MDF Posted March 25, 2014 Share Posted March 25, 2014 (edited) I have a somewhat similar issue. When switching from thermal to day channel there is a significant frame rate loss, which abates after about 1-2 seconds. I would add that performance seems to deteriorate, and this particular issue only rears its ugly head, only after the program has been running for some period of time. For example, I just started SB and jumped into a quick mission, and frame rates were good and consistent between thermal and day channels.I have experienced the issue using both older and most recent Nvidia drivers.System info: Total amount of system memory 16.0 GB RAM System type 64-bit operating system Processor: Intel Core i7-2600K CPU @ 3.4GHz Number of processor cores 4 Total size of hard disk(s) 3726 GB Disk partition © 1582 GB Free (1863 GB Total) Media drive (D) CD/DVD Disk partition (I) 0 B Free (39 MB Total) Disk partition (J) 866 GB Free (1863 GB Total) Display adapter type NVIDIA GeForce GTX 580 Total available graphics memory 4095 MB Dedicated graphics memory 1536 MB Dedicated system memory 0 MB Shared system memory 2559 MB Display adapter driver version 9.18.13.3489 Primary monitor resolution 1920x1080 Secondary monitor resolution 1920x1080 DirectX version DirectX 10 Network Adapter Intel® 82579V Gigabit Network Connection Edited March 25, 2014 by MDF 0 Quote Link to comment Share on other sites More sharing options...
OnAlienware Posted March 25, 2014 Author Share Posted March 25, 2014 Hi Jam, I'm using Nvidia's 335.23 driver on a GTX780M. The problem has persisted over a couple updates. Please help. 0 Quote Link to comment Share on other sites More sharing options...

Members Ssnake Posted March 29, 2014 Members Share Posted March 29, 2014 It's more the question whether you discovered a hidden bug, I think. 0 Quote Link to comment Share on other sites More sharing options...
Rotareneg Posted July 13, 2014 Share Posted July 13, 2014 I had this issue during the last TGIF. My frame rate would often drop for a moment from 30 to around 15 to 25 when switching from the map to the 3D world. I was recording, and thought perhaps that was causing an problem (although it normally doesn't) but it didn't clear up when I stopped to check.

Rotareneg Posted July 13, 2014 Share Posted July 13, 2014 Hmm, it might be the video drivers, as I had just updated to 340.43 for my GTX 760, so I'll revert back to 337.88. 0 Quote Link to comment Share on other sites More sharing options...

AFAIK (and a programmer will correct me if I am wrong), but it is not abnormal that the frame rate is different from the map and 3D world, and by different, I mean a HUGE difference. The fact is, there is a lot less going on in the map view so you should get extremely high fps there, and the 3D world is of course more indicative to what fps you should expect to have.For me, I think I have always gotten 60 fps at the map screen and 30 fps in the 3D world, even before any changes to the GFX engine. If you say that you get just 30 fps at the map, then it does make sense that it would be around 15 fps in the 3D world view. What would be a bug is if you consistently get more than that in the 3D world view, and it only dips to 15 fps just after exiting the map, for a temporary amount of time. 0 Quote Link to comment Share on other sites More sharing options...

So you are saying that the drop in fps in the 3D world view actually IS temporary? If so, then that would be very strange, yes, as long as you are saying the fps raises again while in 3D world view (it is normal that it fps would increase when entering the map though, AFAIK). 0 Quote Link to comment Share on other sites More sharing options...
Lt DeFault Posted July 13, 2014 Share Posted July 13, 2014 So you are saying that the drop in fps in the 3D world view actually IS temporary?It is for me. It only lasts a split second. It doesn't seem to happen every time, though. I'll do some testing and maybe post a vid here soon. 0 Quote Link to comment Share on other sites More sharing options...
Rotareneg Posted July 13, 2014 Share Posted July 13, 2014 Yes, the frame rate drop when switching from the map to observer view was often only momentary, returning to normal after several seconds or so, and it didn't always happen. I hadn't had this happen (or at least I hadn't noticed it) for quite a while, and then it started again after installing the 340.43 drivers which is what makes me suspicious it might be a driver bug or conflict with something SB does. Tomorrow I'll see if I can get it to happen again with the 340.43 drivers.Also, I would normally be getting well above 30 FPS, but I use my video capture software to limit the frame rate at 30 fps as that's all YouTube's good for right now anyway. When I stopped recording to see if that would help, I was getting the full ~60 fps on the map, which would then would drop to around 30 or so when I switched to a vehicle before jumping back up to 50 or 60, depending on what was on the screen. 0 Quote Link to comment Share on other sites More sharing options...
Lt DeFault Posted July 13, 2014 Share Posted July 13, 2014 I just noticed it might be related to the amount of time spent in the map view. Perhaps it has something to do with "new" terrain having to be rendered? I'll keep experimenting and report back. 0 Quote Link to comment Share on other sites More sharing options...
Rotareneg Posted July 13, 2014 Share Posted July 13, 2014 I couldn't get it to happen again, including while recording, so who knows. 0 Quote Link to comment Share on other sites More sharing options...

OnAlienware Posted October 14, 2014 Author Share Posted October 14, 2014 (edited) Hey, gents:After an absence (and many driver updates), my performance issues are still here, but different. My frame rates rather suspiciously seem to lock in at 20, 30 or 60fps, and the trigger for these rates seems to be changing views.I love SB. This is killing me. Please help.

Members Ssnake Posted October 14, 2014 Members Share Posted October 14, 2014 Do you have vertical synchronization activated? 0 Quote Link to comment Share on other sites More sharing options...
OnAlienware Posted November 13, 2014 Author Share Posted November 13, 2014 Hi Ssnake,I disabled V-sync globally, and preliminarily, it seems to have solved the problem. The default setting is to honor the application setting, which SB doesn't seem to have. Is there a fix on the way?Thanks! 0 Quote Link to comment Share on other sites More sharing options...
Members Ssnake Posted November 13, 2014 Members Share Posted November 13, 2014 We have no specific plans, but if it isn't too hard to implement (I don't think so) I'll see if we can do so with the next PE update. 0 Quote Link to comment Share on other sites More sharing options...
Rotareneg Posted November 13, 2014 Share Posted November 13, 2014 Huh, I wonder if it's a Windows 8 thing as I'm running a GTX 760 on Windows 7 and the SB vsync setting works as expected. 0 Quote Link to comment Share on other sites More sharing options...
Cougar11 Posted November 13, 2014 Share Posted November 13, 2014 I am running a MSI GTX 760 Twin Frozor on windows 8.1 and have no issues with all default settings for system, and graphics. I have heard about issues with the new graphics drivers running the cards hot, and having some issues. 0 Quote Link to comment Share on other sites More sharing options...
