    P3DV4.4:Blurry textures - specific I7-4770K

    Having tried just about all the well-advertised tweaks in the .cfg file to eliminate blurries (none of them worked), I was surprised to discover that HT on does indeed produce crisp results compared to HT off. I run an ancient Intel i7 875K processor with overclocked Turbo Boost (to about 4GHz) using the Intel Extreme Tuning Utility (I cannot overclock in the BIOS as I have a MSI motherboard which is derived from an old HP desktop PC and strictly prohibits overclocking by such means). I do not set an affinity mask in the .cfg file but instead use a free tool called coreprio by Bitsum which enables some element of prioritised CPU affinity which is not strictly permanent in the sim (I have found that the affinity may not be required everywhere in the running of the sim and hence this provides real-time management of CPU affinity priority, only employing the scheme when the CPU load demands it); most other CPU affinity management is permanent and non-variable if set either through an affinity mask in the .cfg file or within the operating system itself, or indeed using Bitsum's Process Lasso. The settings in the coreprio program are a little experimental but with care a good compromise can be reached to optimise CPU performance. The results thus far are very promising and exactly what I have been trying to achieve with my hardware. Finally, it does beg the question why hasn't HT on been flagged up more often for providing a much crisper response in the sim to the loading of scenery? It could be that it may work with older generation processors such as mine but not with the latest generation processors which may well cope without much requirement for adjustment (although I do laugh when people report extreme problems with significantly better and more powerful hardware than mine!). Whether or not these benefits are as intended by greater use of multi-threading in Prepar3D v4.4 is unclear, although I have not heard any reports to that effect that LM have achieved this successfully. Also, the main gripe by some people is that HT on reduces performance (mainly fps) compared with HT off. I for one have found little such loss but admittedly with careful CPU management as described above (which could be the key). I don't think that my investigations are the result of a placebo effect and there is quite definitely a marked improvement of the enjoyment and immersitivity within the sim itself. I am sure we are all slightly crazy demanding the best of everything in the sim squeezed out of the obvious limitations of home-use desktop PC equipment when it may well be the case that the highly expensive airline-standard simulators probably pay little attention to the physical accuracy of the view outside: indeed, these airline simulators are not for "joy rides" and are rather more professional training mediums for practicing procedures and dealing with emergencies etc. Anyway, that is my encouraging experience with HT on!

    Does 1/2 refresh rate work?

    I have just had a fiddle with NVI and the frame rate limiter. In my case it does not seem to constrain the fps to that selected as effectively as Riva Tuner Statistics Server (RTSS), with NVI bringing about excursions to 37fps with a limit set of 30fps. RTSS does not do this.

    Does 1/2 refresh rate work?

    One further thing, Matt, is that you should keep Riva Tuner Statistics Server running once having set the frame rate. In order to set frame rate in RTSS, enter e.g. 30 in the appropriate box which will flash, press enter to select it and then minimize RTSS (do not close it down). RTSS runs in the background and you will find that the frame rate stays locked in P3D (although of course set as unlimited in P3D itself).

    Does 1/2 refresh rate work?

    Matt, yes my apologies, I do indeed have G-Sync switched on.

    Does 1/2 refresh rate work?

    I thought I would just add my experience of setting a locked frame rate. I have a Freesync monitor set at 144Hz refresh rate, which uses Nvidia G-Sync by way of the latest Nvidia drivers. I have frame rate set as unlimited in Prepar3D v4.4, but lock the frame rate to 30fps using Riva Tuner Statistics server (RTSS). Provided that you set the frame rate in RTSS before you run P3D, the frame rate is indeed locked in P3D itself (although set as unlimited) and there are no penalties associated with such frame rate locking: i.e. if without frame rate locking 40-50 fps was usually achieved, the frame rate is solid at about 30fps with frame rate locking through RTSS and not say 20-25fps or less if you had frame rate locked at 30fps from within P3D itself. I also find that it may be necessary to set VSync to ON within Nvidia Control Panel, which seems to be a recommendation by AMD for the use of Freesync with their monitors, to eliminate some minor stuttering. In this way, my own experience is one of very smooth performance indeed, with a marked reduction in stutters and also better control of what might have otherwise been a fairly widely-varying frame rate. That is not to say that anyone else will experience the same in so doing, but spreading the knowledge may help some.

    TE Netherlands - updated

    Four minutes for me with my ancient PC. Must be doing something wrong!

    TE Netherlands - updated

    Does anyone know if the compatibility problems associated with FlyTampa Amsterdam still need addressing as reported in the Orbx forum? I presume so since not everyone would intend to use a payware addon for the airport.
  8. I am inclined to agree that the main emphasis does appear to be directed towards AMD CPUs, but the basic functionality does seem to read across to my older generation Intel processor very nicely. There appears to be no other tool out there which can perform the same operations on CPU affinity if it is more desirable to utilize a soft CPU affinity rather than something set non-dynamically.
  9. I thought that I would bring a free software tool to the attention of Prepar3D users called CorePrio by Bitsum. The software uses Dynamic Local Mode (DLM) which is Bitsum's implementation of AMD's Dynamic Local Mode. Bitsum describes DLM as follows: "DLM works by dynamically migrating the most active software threads to the prioritized CPU cores. The Windows CPU scheduler is free to choose specifically where within that set of CPUs to assign threads. Since no hard CPU affinity is set, applications are still free to expand across the entire CPU. For this reason, we call it a prioritized soft CPU affinity. DLM is designed for loads that don’t max out all available CPU cores. Applications that put a full load across the entire CPU could perform marginally worse. This is because when the entire CPU is loaded, there are no CPU cores to prioritize threads to since all must be utilized. Thus it may be ideal to exclude some highly multi-threaded applications." With my dated, Intel i7 875K processor (I am not made of money for the latest and greatest!), I am experiencing much better and smoother performance in Prepar3D v4.4. It would appear that, under certain circumstances with my CPU, Core 0 is maxed out and you can enable Bitsum's Dynamic Local Mode in Coreprio to prioritize the CPU affinity to say Cores 1-3. This is not the same as setting a default CPU affinity, i.e. not a hard CPU affinity but a soft one instead, and applications are still free to expand across the entire CPU. This has resulted in my case with much more efficient CPU usage and comparatively, exceptionally smoother performance in Prepar3d v4.4 itself even at lower frame rates down to say 20 fps. Whereas this may not be a magic bullet for all systems, in my case I can vouch for the improvements and what is more it is absolutely free. Jeremy Collake of Bitsum has advised me he may be thinking of incorporating Coreprio into the more well-known Process Lasso software, but only as a largely standalone offshoot from it. So, go ahead and experiment yourself if you feel your system may benefit from the CPU affinity prioritization and what is more it is free to download and use. Finally, I do not use an Affiinity Mask in the Prepar3D.cfg file. I simply found it caused too many blurries in the scenery and what is more it is a hard CPU affinity and does not allow Prepar3D to expand across the entire CPU.
  10. My problems with the Nvidia drivers are post-417.75 with G-Sync. I have a (Nvidia non-compatible) Freesync monitor (Acer XZ321QU) which I can now use with G-Sync using Nvidia drivers 417.71 and above. The problem with the latest post-417.75 drivers with my monitor is that, at 144Hz refresh rate, the use of G-Sync causes regular, annoying black screens lasting anywhere up to 3 seconds either in windowed or full screen mode in either Prepar3D v4.4 or X-Plane 11. The solution is to use a lower refresh rate, i.e. 120Hz, or go back to earlier drivers such as 417.75 which work at 144Hz refresh rate. It is obviously the case that Nvidia has broken the drivers where compatibility with my monitor is concerned rather than a hardware-related fault directly. Hopefully this problem will be fixed in a later driver release. G-Sync with low frame compensation (we are not in the business of matching directly a 144Hz refresh rate with the fps from Prepar3D v4.4 or X-Plane 11!), does seem to improve the smoothness of Prepar3D v4.4 in particular, although I do experience stutters in X-Plane 11.32r2. The use of V-Sync by way of the Nvidia Control Panel in Prepar3D v4.4 does also seem to reduce issues with stutters (as recommended by AMD with a Freesync monitor). Anyway, good for Nvidia for making a Freesync monitor useable with Nvidia G-Sync if you have a compatible graphics card (I thought I had made an expensive mistake with the initial incompatibility between Freesync and an Nvidia graphics card), but not so for occasionally breaking things with their drivers.

    Freeware Trent 500 sounds for p3dv4.

    I believe that I am correct in saying that there is a sound issue in the Blackbox A330/A340 which has been acknowledged by the developer. Hence no amount of tweaking on the part of the user community can resolve this issue, even with a new set of sounds for the Trent engine since it seems to be hard-coded into the model. Hopefully when the product is updated soon as the developer has pledged (with a number of enhancements), then this sound issue will have been resolved.
  12. When I check for encoding errors in P4AO, I get a message identifying an incorrect character encoding in C:\ProgramData\Lockheed Martin\Prepar3D v4\add-ons.cfg file. Is this normal and can it ignored?

    ORBX True Earth GB / FPS insane killer!

    Didn't quite follow your logic. What has actually been replaced (if at all) to accommodate the Prealsoft London VFR AG in the Orbx GB scenery/texture files?
